What is Calcium hydride? Calcium hydride is an inorganic compound with the chemical formula of CaH2. It is a white crystalline powder, insoluble in carbon disulfide and slightly soluble in concentrated acid. It is mainly used as a reducing agent, desiccant, and chemical analysis reagent.
Uses of Calcium hydride powder Used in powder metallurgy, when heated to 600 ~ 1000℃, it can be reduced with metal oxides such as zirconium, niobium, and hafnium to obtain the corresponding metal powder. It can be used as a portable hydrogen generator, reducing agent, desiccant, and analytical reagent. Preparation of Calcium hydride Refined calcium with a purity of about 99. 5% was put into an iron plate and placed in the center of the Shi Ying reaction tube. At both ends of the Shi Ying reaction tube, an air inlet pipe and an air outlet pipe were respectively installed with rubber plugs, and purified hydrogen was introduced from the air inlet pipe, and the air outlet pipe was connected with a fume hood through a mineral oil bubbler. The reaction tube is heated by an electric furnace. At first, a large amount of hydrogen was introducedinto the purified hydrogen to replace the air in the reaction system, and then it was heated by an electric furnace. The reaction started at about 200℃ and was further heated to 250 ~ 300℃. Hydrogen was introduced at a flow rate of 0.6mL/min for the reaction, and it took about 2 hours to complete. The generated calcium hydride was a porous gray crystal powder, and the purity of the prepared calcium hydride was about 99%. Properties of Calcium hydride Calcium hydride belongs to the colorless orthorhombic crystal system; The substance is gray, orthorhombic, or powder. Sensitive to moisture. The relative density is 1.90. The melting point is 816℃ (in hydrogen). It decomposes into Ca and H2 at 600℃. When it decomposes in water, it releases hydrogen, and it can also react with ethanol to generate hydrogen and calcium ethoxide. The reduction of metal oxides is stronger than that of sodium hydride or lithium hydride. Price of Calcium hydride powder Calcium hydride powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Calcium hydride powder. A large amount of large amount will be lower. The price of Calcium hydride powder can be found on our company's official website. Calcium hydride powder supplier Luoyang Tongrun Nano Technology Co.
