What is calcium hydride? Calcium hydride is a chemical substance, the laboratory uses CA and H2 to respond under heating conditions to generate CAH2. CAH2 is a compound of ion. CAH2's Chinese name is calcium hydride. The molecular formula of CAH2 is CAH2, gray -white crystals or blocks, which are easy to deflect, the molecular weight is 42.10, melting point: 675 ° C (decomposition) (decomposition), insoluble for sulfide) 1.7, the main purpose: as a reducing agent, a desiccant chemical chemical chemistry Analysis reagent, etc.
Function and use of calcium hydride It is decomposed into Ca and H2 at 600 ℃. 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. React violently with water to produce H2 gas. CaH2 prepared by the above method has a high heat of formation.
Safety of calcium hydride In case of possible contact with poisons, you should wear a hood-type electric air supply filter dust respirator. If necessary, it is recommended to wear self-contained breathing apparatus, Wear chemical protective clothing, and rubber gloves Smoking is prohibited at the work site; Pay attention to personal hygiene. Skin contact: immediately remove contaminated clothing and wash them with plenty of flowing water for at least 15 minutes. Get medical attention. Eye contact: immediately lift the eyelids and rinse thoroughly with a large amount of flowing water or physiological saline for at least 15 minutes. Get medical attention. Inhalation: quickly leave the site to fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, carry out artificial respiration immediately. Get medical attention. Ingestion: Rinse mouth with water and drink milk or egg white. Get medical attention. Extinguishing method: Do not use water, foam, carbon dioxide, halo hydrocarbon (such as 1211 extinguishing agent), etc. Only use a metal cover, dry graphite, or dry dolomite powder to simmer the fire.
Storage method of calcium hydride Store in a cool, dry, well-ventilated special warehouse, away from kindling and heat sources. The temperature of the warehouse shall not exceed 32 ℃, and the relative humidity shall not exceed 75%. The package must be sealed and free from moisture. It should be stored separately from oxidants, acids, alcohols, halogens, etc., and should not be mixed. Explosion-proof lighting and ventilation facilities shall be adopted. Using mechanical equipment and tools that are easy to produce sparks is forbidden. The storage area shall be equipped with appropriate materials to contain the leakage.
Price of calcium hydride Calcium hydride particle size and purity will affect the product's price, and the purchase volume can also affect the cost of calcium hydride. A large amount of large amount will be lower. The price of calcium hydride can be found on our company's official website.
