invar tube is a nickel-iron alloy that is noted for its uniquely low coefficient of thermal expansion. It contains 36% nickel and has a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 400degF (204degC).Invar is used in applications requiring high dimensional stability for large,...
dibasic calcium phosphate anhydrous is a white, tasteless, and free flowing powder that is used in various food, pharmaceutical and cosmetic products as a calcium and phosphorus nutrient. It is commonly found in nutritional beverages, dough and bakery mixes, pet food, infant formulas, vitamin tablets, and toothpaste formulations.The minerals calcium...
Sodium acetate is an anhydrous form of acetic acid. It is a common reagent for acid-base equilibria in solution. It is also a buffer to maintain the pH of a solution. Sodium acetate is used as a source of carbon for culturing bacteria. It is also a photoresist for aniline...
The melting point of lead is one of the most important temperatures in metals, as it can be used to determine a metal’s ability to withstand high-temperature environments. If a metal is unable to withstand a particular temperature, it can fail or break down, causing damage to the component and...
antifogging agent is a chemical that prevents fogging of glass or plastic surfaces, commonly used for lenses and mirrors on glasses, goggles, camera lenses and binoculars. They work by minimizing surface tension, resulting in a non-scattering film of water instead of individual droplets. Aside from the fact that anti-fogging agents...
The density of a substance is the total mass divided by the volume of the occupied space. Density is typically measured in units of kilograms per cubic meter (kg/m3) or pounds per cubic foot (lbm/ft3).The atomic weight of an element is a factor that contributes to the density. The atomic...
cadmium carbide is a mineral, which is used in the production of acetylene gas. This chemical is also used as a raw material for the manufacture of other chemicals like vinyl chloride, acrylonitrile, acetone, ethylene, and styrene.Originally, acetylene was produced in the same way as calcium carbide. The reaction was...
vanadium iii sulfate is an inorganic compound with the formula V 2 (SO 4 ) 3. It is a pale yellow solid that is stable to air but slowly dissolves in water to produce the green aquo complex [V(H2O)6]3+.It is a reducing agent and is useful for making organic light...
how many neutrons does hassium have?Hassium belongs to the d-block of periodic table and is a radioactive element. It is a transition metal that is classified as a Group 8 element.The atomic number of Hassium is 108. This number is equal to the total number of protons in the atom.Neutrons...
Does zinc rust?Yes, but not in the same way as other metalsZinc oxidises slowly to form a protective layer that protects the underlying steel from further corrosion. This is called hot-dipped galvanizing and can be achieved through various methods.The most common method is hot-dip galvanizing, which involves submerging the steel...
