BeF2, also known as Beryllium fluoride, is a chemical compound consisting of two fluorine atoms and one beryllium atom. In English, it is called Beryllium fluoride. This compound has a molar mass of 47.01 g/mol. The BeF2 molecule is formed from one beryllium ion (Be2+) and two fluorine ions (F-).
Physically, BeF2 is usually a white crystalline substance without a distinct odor. It does not dissolve in water at room temperature, but can dissolve in water at higher temperatures. BeF2 has strong chemical properties, capable of reacting with certain metals and non-metals to form other substances.
BeF2 can be synthesized through the reaction between beryllium and fluorine under high temperature conditions. In the lab, you can synthesize BeF2 by passing fluorine over heated beryllium. On an industrial scale, BeF2 is typically produced from the thermal decomposition of beryllium hydrofluorite (Be(HF2)2) at temperatures of 900-1000 °C.
BeF2 can react with metals such as sodium to form sodium beryllofluoride. It can also react with acids, such as nitric acid, to form beryllium nitrate and fluorine. BeF2 can also react with non-metals like chlorine to form beryllium chloride and fluorine.
