Description of CALCIUM HYDRIDE
Hydrolete is the chemical compound with the formula CaH2. This grey powder (white if pure, which is rare) reacts vigorously with water liberating hydrogen gas. CaH2 is thus used as a drying agent, i.e. a desiccant.
CaH2 is a saline hydride, meaning that its structure is salt-like. The alkali metals and the alkaline earth metals all form saline hydrides. A well-known example is sodium hydride, which crystallizes in the NaCl motif. These species are insoluble in all solvents with which they do not react. CaH2 crystallizes in the PbCl2 (cotunnite) structure.

What is CALCIUM HYDRIDE?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is it which has developed particularly rapidly in recent years. Do you know about it?
The official answer:Hydrolete is an inorganic substance with the chemical formula CaH2 and a molecular weight of 42.10. Off-white crystals or lumps, very easily deliquescent, used as reducing agents, desiccants, reagents for chemical analysis, etc.; also colorless rhombohedral crystals; industrial products are grey, orthocrystals, or powder.
What’s the application of CALCIUM HYDRIDE?
Used in powder metallurgy, when heated to 600-1000°C, 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, as a drying agent, and as an analytical reagent.
