Arise New Material supplies high-quality Calcium Hydride CAS 7789-78-8 to chemical, metallurgical and laboratory customers around the world. Calcium hydride is an alkaline earth metal hydride with strong reducing power and excellent water-scavenging ability, making the compound a practical workhorse in both industrial processes and research laboratories. This article summarizes the properties, main applications and safe storage of Calcium Hydride CAS 7789-78-8.
Calcium hydride is a white to gray crystalline powder or lump produced by the reaction of calcium metal with hydrogen at elevated temperature. The compound is thermodynamically stable in dry air but reacts readily with water to release hydrogen gas and form calcium hydroxide. Because of its high hydrogen content and reducing ability, Calcium Hydride CAS 7789-78-8 is widely used as a portable hydrogen source and a powerful reductant.
Calcium hydride has a density of about 1.9 g/cm³ and decomposes at temperatures above roughly 600 ℃, with a melting point near 816 ℃ under hydrogen. The compound is insoluble in ether and reacts with water, carboxylic acids and lower alcohols to generate hydrogen. One gram of Calcium Hydride CAS 7789-78-8 can release approximately one liter of hydrogen when reacted with water, which explains its long-standing use in field hydrogen generation.
Calcium Hydride CAS 7789-78-8 reduces metal oxides and metal chlorides of zirconium, niobium, uranium and chromium to the corresponding metal powders at 600-1000 ℃. In organic synthesis, the compound serves as a strong reducing agent and condensing agent for selected transformations. These applications make Calcium Hydride a key material for metal powder production and specialty synthesis.
Calcium hydride is one of the most convenient drying agents for organic solvents, especially amines, pyridine and other basic solvents, and is frequently used to pre-dry solvents before more reactive desiccants are applied. The compound is also used to generate small quantities of high-purity hydrogen for experiments and to inflate weather balloons in the field. For bulk users, Calcium Hydride CAS 7789-78-8 offers a safe, solid and easy-to-transport form of hydrogen.
Because Calcium Hydride reacts vigorously with water, keep the product in tightly sealed, moisture-proof containers in a cool, dry and well-ventilated area. Avoid contact with water, acids and alcohol, and keep away from open flames because the released hydrogen is highly flammable. Under proper storage, Calcium Hydride CAS 7789-78-8 maintains its activity for extended periods.
