P-type silica particles are divided according to the structure of nanometers. P-type silica particles are distinguished by their large number of nanopores. Their porosity is 0.61 mL/g and have higher UV reflectivity than S type particles. They also have a very small surface area.
Nano silica features a light volume, fluffy bulk density, less than 0.15-0.2g/cm3, an area specific of more than 500m2/g, high chemical activity, and a large surface area.
The surface of nano silica contains an OH bond. This makes it a silicate acid group type. The water absorption rate is greater than 5x its own.
Silica nanoparticles have many uses. They are used as additives in rubber, plastic manufacturing, reinforced fillers for concrete, and as a platform for biomedical purposes such as drug delivery or therapeutic diagnostics.
What is Silica?
Silicon (or simply silicon) is one of the many chemical elements found in the earth’s crust. It can be found in silicate (SiO4) or silicon dioxide (silica and SiO2).
It is common to use silicon in industry. The oxide form of silicon is often used in biomedical and industrial applications. SiNPs are rare because of their unique properties. These include ease of synthesis and surface modification, strong mechanical property, and relatively inert chemical structure. They have been used in biological materials for many decades.
Silica can be found in two forms, crystalline and amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Crystalline silica features a regular lattice arrangement while amorphous is more irregular. Crystalline silica can be found in many forms. Alpha-quartz is the most well-known, which can then be converted to b –quartz, squamous, or quartzite by heating. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Because of their rare properties (high surface area, high pore volume and adjustable pore size), silica and Mesoporous Silicon are excellent candidates for controlled drug delivery. There are three main types of amorphous silicon: natural, byproducts, and synthetic. Amorphous silica has been considered a promising candidate to carry genes and perform molecular imaging. This is due to its high-tunable biocompatibility as well as stability. It is used in dental fillers, dental implants, dietary supplements and catheters.
What uses is nanosilica?
Nano silica can be used to modify cement concrete’s dispersion, plasticity, and thus increase its impermeability, enhanced permeability, frost resistance and reduce hydration heat. It also prolongs the service life.
It can be used as a vitrification agent, strengthening agent, adhesive, and glue of ceramics, enamels and glazes. It can also be used to make engineering-grade ceramics and other refractories.
Use nanocomposite materials modifier as an inorganic adhesive at high temperature. Also used to strengthen, mold and fill rubber/polymer material. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
It can be used to cement seal an oil well or as an under-ground seal and reinforcement material.
Use for special purposes, including lamp paint, lubricating oil, thickener or steel dehydrogenate and inner wall paint sensitive material. For solar cells and power cell energy storage.
Is nano-silica toxic?
Exposed to silica, particularly crystalline, has been extensively researched.
Studies have shown that workers are exposed to crystalline silicona at work, which can lead to silicosis. This is a fibrotic lung condition that can also be caused by other diseases such as lung cancer, emphysema, or tuberculosis.
Amorphous silica used to be considered less toxic than crystalline. Recent research has shown that SNPs that are amorphous have toxicity levels similar to crystalline particles. SiNPs’ physicochemical and crystallinity also produce different levels of toxicity in vitro as well as in vivo. Consider safety and possible adverse effects, especially those that may affect the immune system.
