氟化钙颗粒(CaF2)essential information | |
Molecular formula | CaF2 |
purity | 99.99% |
CAS No | 7789-75-5 |
Molar mass | 78.075 |
density | 3.18 g/cm³ |
melting point | 1402 ℃ |
boiling point | 2500 ℃ |
Solubility (water) | 极难溶于水。可溶于盐酸、氢氟酸、硫酸、硝酸和铵盐溶液,不溶于丙酮。 |
无色结晶晶颗粒,一般采用钨、钼、钽材制作的蒸发舟或坩埚。
属等轴晶系,呈立方体、八面体或者十二面体。
附加:一般的CaF2为无色结晶或白色粉末,天然矿石中含有杂质,略带绿色或紫色,加热时发光。溶于铝盐和铁盐溶液时形成络合物,与热的浓硫酸作用生成氢氟酸。氟化钙跟浓硫酸在铅制容器中反应可制得氟化氢。能与多种金属氧化物形成低共熔物。
