Main Uses:

 

Used in powder metallurgy, when heated to 600 ~ 1000ºC, it can be reduced with zirconium, niobium, hafnium and other metal oxides to obtain the corresponding metal powder. It can be used as a lightweight hydrogen generator, as a reducing agent, desiccant, and analytical reagent.

1.Hydrogen generating agent, reducing agent, desiccant, analytical reagent.
2.It is used as reducing agent and shrinking agent in organic synthesis, as desiccant and hydrogen production material.
3.Used as reducing agent to reduce rare metal oxides to prepare rare metals, liquid and gas desiccant, chemical analysis reagents, etc. Organic synthesis.

 

Properties:
1. Appearance: Calcium hydride is grayish white to grayish black crystal or powdery substance.
2. Stability: Relatively stable at room temperature, but will react with moisture and water to produce hydrogen and calcium hydroxide. 3. Soluble: Calcium hydride is dissolved in water to a limited extent, forming calcium hydroxide and releasing hydrogen.

Uses:
1. Dehydrating agent: calcium hydride is commonly used as a dehydrating agent in industry, which can absorb moisture in the air.
2. Hydrogen source: Calcium hydride can react with water to produce hydrogen and can be used as a source of hydrogen.
3. Gas generator in the air bag: Calcium hydride can react with acid to produce hydrogen gas, which is often used as a gas generator in the air bag.
