    What is Alumina Nanoparticle used for?

    The coating material for the lithium battery's diaphragm is High purity micro alumina. This ceramic coating acts as heat resistance and insulation to protect the battery from being shorted by high temperature or diaphragm melt.

    Additional ingredients for lithium battery cathode materials:
    Doped with lithium cobalt, lithium manganate, high-purity nanoalumina can increase thermal stability and cycle performance, prevent the formation of oxygen, the decomposition LiPF6, and reduce direct contact between LiCo02 (electrolyte) and LiCo02. It also increases the electrochemical specificity of LiCoO2.

    Catalyst:
    A porous material with high purity of g type nano-alumina has a surface area of many hundred of meters per gram. It also exhibits high activity and strong absorption capabilities. It's a common adsorbent, catalyst, and carrier in the petroleum refining, petrochemical, and oil industry.

    Powder coating Anti-caking:
    Summer can be prevented by nano-alumina. The use of nanometer aluminum trioxide in powder coatings is a great way to improve powder coatings' fluffiness. It also has a good anti-caking property. This powder coating is stable in extreme temperatures or high humidity environments.

    Hardening and wear-resistant coating for rubber or plastics:
    Nano-alumina can increase the durability and resistance to scratches of the coating by adding between 2-50%. The paint can have a fine network structure that protects the paint's surface from scratches and wear by adding nano-alumina to it. The scratch resistance of nanopaint is three times better than original paint. This paint is commonly used for automobile paints, such as the GM-Aluminum Trioxide. A nano-aluminum triooxide is able to significantly increase the hardness and can even reach as high as 6-7H. It does not affect the transparency of coating.

    Plastics, rubber, adhesives, paint thermal conductivity:
    One crystal Alumina thermal conductivity (30 nanometers alumina), high thermal conductivity, large-spherical filling. Surface treatment agents like coupling agents can be used to improve thermal conductivity. They are often used in order to improve compatibility with resin matrix fillers and other matrix materials.

    Ceramic:
    High purity and uniform size of the nano-alumina particles make it a great choice for dispersion. If 10% of alumina is added into the sintered ceramics it increases the forming pressure, which may reduce the number pores. This can also increase the density of ceramic blanks.

    Powdermetallurgy
    The nano alumina used in metallurgy is small in size with a high specific surface area.

    Polishing:
    These alumina particles have uniform sphericity and can be used for polishing. Polishing zinc is fast, bright, and without scratches.

    Spherical Alumina Powder And The Applications of Spherical Alumina

    One of the thermal conductive material is aluminum. Spherical aluminum oxide A "star" material. The use of spherical-shaped alumina in thermal management fields, such as 5G, is a good idea. This market is expanding rapidly. Spherical Alumina is widely used not only as a thermal conductive substance but also in advanced ceramics, catalysis and grinding, polishing and composite materials.

    Spherical Al2O3 Property

    Because of their many crystal shapes and unique chemical and physical properties, Alumina and its Hydrate are used widely in electronics, petrochemical, refractories as well as papermaking and pharmaceuticals. Alumina's application capabilities in many areas are directly related to their morphology. The Al2O3 powders of different sizes have various morphologies. However, the Al2O3 spheres are more uniform in morphology.

    Spherical Application

    Used as Spherical Allumina Powder Thermal Conductive Materials The most significant use of spherical aluminum is thermal conductive material. Spherical alumina can be classified as thermal interface material, thermal-conductive engineering plastics and thermally conductive plastic sealing substances. The thermal interface materials can be used to IC packaging or electronic heat loss. These materials fill in any gaps caused by contact between the materials. This reduces the heat transfer resistance and improves heat dissipation. Inorganic thermal filler sphere alumina is common. Its thermal conductivity can reach 3042W/m K.

    Ceramics using Spherical Allumina Powder
    The properties of ceramics can be greatly affected by adding a small amount of spherical aluminum powder to their production. Low temperature brittleness in ceramics has a significant impact on their ability to be used for various purposes. For low-temperature plastic ceramics, you can use ceramic materials with spherical aluminum powder. Additionally, ceramics can be made tougher by using spherical-alumina. It can increase the ceramics' strength and decrease the melting temperature by reducing the amount of spherical allumina powder to 5.0%.

    As a polishing agent, use Spherical Allumina Powder
    Spherical or flake-alumina alumina offers better fluidity and dispersion than conventional granular or flake. Because spheres of alumina powder are evenly distributed within polished products, there is no possibility for powder to accumulate in large quantities. The particle surface can also be smooth, which helps avoid scratches and improves polishing.

    Spherical Led luminaire Use Both its catalyst and its transporter
    High chemical activity is possible because of the large amount of unsaturated chemical bonding and catalytic activ centers that are found on the surface. Spherical Alumina offers the benefits of high chemical activity, low wear, and long service lives. It also boasts a large specific area. It is impossible to replace the performance and characteristics of the catalyst made of spherical aluminum with other materials.

    Spherical Alumina Use in 3D printing
    Due to its strong strength, high spheroidization rate and resistance to high temperatures, 3D printing is a popular use of sphered-alumina. The advantages of spherical allumina powder include high solid content and good fluidity. They also have high mechanical and chemical properties.

    Aluminum Oxide Used for lithium battery Diaphragm

    What is a ceramic diaphragm. A special ceramic coating diaphragm uses PP,PE or multi-layer composite as the matrix. The surface of the diaphragm is then coated with a nano-sized layer made from aluminum oxide. This is then bonded tightly to the substrate by special processes. The high temperature safety and reliability of lithium-ion cells can be significantly improved by using this coating. A ceramic-coated special diaphragm can be used for power batteries.

    Specifications for diaphragms to charge lithium-ion batteries with lithium-ion:
    The diaphragm's performance determines the interface structure and internal resistance of the battery. This determines its capacity, safety performance, charge density, and performance during a cycle.

    These characteristics must be fulfilled:
    Chemical stability is excellent: Resistance to organic solvents.
    Excellent mechanical properties, high tensile strengths and high puncture resistance.
    Excellent thermal stability. Low thermal shrinkage. High film breaking temperature.
    The electrolyte's wettability is good for compatibility and low liquid absorption.

    aluminium oxide, a type of inorganic material, is good for ceramic coatings on battery diaphragms.

    Ceramic diaphragm for Alumina:
    1. Particle size is consistent, so they can be glued well to the diaphragm.
    2. Alumina's purity is high and it can be used without introducing impurities that could affect the internal environment of the batteries.
    3. It is necessary for alumina crystal to be compatible with an electrolyte.

    Benefits of coating aluminum diaphragm:
    Resilience to extreme temperatures
    It is resistant to extreme high temperatures, and retains its original shape above 180 degrees Celsius.

    Secure:
    An alumina-coated battery can reduce the levels of HF and increase safety and acid resistance.

    High magnification
    A solid solution of nano-alumina is possible in lithium batteries, which will improve magnification and cycling performance.

    Good wettability:
    Nanometer-sized alumina powder is very liquid absorbent and retains liquid well.

    Unique self-turn-off characteristics:
    Polyolefin diaphragms have a closed-cell design to prevent thermal runaway.

    Low self-discharge rate:
    Because of its curvature, micropores are more curvy with alumina than they would be without the coating. Also, self-discharge rates of alumina coated diaphragms are lower than those of common diaphragms.

    Increase the lifespan of the cycles by increasing the number of cycle lives.
