formula of calcium nitride
The formula of calcium nitride is Ca3N2, with calcium and nitrogen in a 3:2 ratio. It is a white, odorless powder that has a melting point of 1,721 degC and a boiling point of 2,450 degC.
It is a significant chemical reagent and has many important applications. It can be used to produce reactive nitride ions and is also an essential component in hydrogen storage research and advanced fuel cells.
A wide variety of products can be made from this compound, including catalysts and reagents, and optical and electrical materials. It is also a key ingredient in the production of high-end phosphors that provide improved performance, stability and resistance to harsh environments.
One of the most common synthesis methods is to use elemental calcium in a nitrogen stream heated to 450deg C. This results in a precipitate of calcium nitride that is readily available in pure powder form.
Other synthesis methods include the reaction of calcium oxide or hydroxide with ammonia, and the reaction of carbonate with ammonia. These methods produce a different type of powder that is also composed of calcium nitride, and can be useful for some research purposes.
Scientific research application
Calcium nitride is the primary raw material for producing high-end phosphors. These phosphors can be produced in a wide range of sizes and can be used to create a wide variety of materials, including microchips, optical fibers and electrochromic displays.
