Introduction to Calcium Molybdate
Calcium Molybdate, a chemical compound with the formula CaMoO4, is a primary source of molybdenum that is vital to several industrial applications. It is derived from the combination of calcium and molybdenum elements, both of which are highly valuable in various industries and biological processes. Despite its seemingly simple structure, this compound is the cornerstone of numerous applications, ranging from ceramics manufacturing to the production of high-strength steel.
Chemical and Physical Properties
Calcium Molybdate is characterized by its high melting point, which is around 1643°C. The compound typically exists in a crystalline state and is an odorless, white powder at room temperature. Its specific gravity is approximately 4.35, and it exhibits poor solubility in water, alcohol, and other common solvents.
When heated, Calcium Molybdate decomposes to release oxygen and forms a variety of other molybdenum compounds. Due to its stable nature, it does not readily react with other elements or compounds at room temperature.
