方解石

白色粉末，不溶于水，易溶于酸，晶体属三方晶系的碳酸盐矿物。晶体常为复三方偏三角面体或菱面体与六面体的聚形，集合体多呈粒状、块状、钟乳状、鲕状、纤维状及晶簇状等。通常为无色、乳白色，优质方解石经超细粉碎、分级，得到系列不同细度的超细粉体，简称超细重钙粉。广泛用于涂料、塑料、油漆、橡胶、造纸、牙膏、医药和日用化工等产品中作填充料。 方解石的化学成分为Ca[CO3]，晶体属三方晶系的碳酸盐矿物。晶体常为复三方偏三角面体或菱面体与六面体的聚形，集合体多呈粒状、块状、锺乳状、鲕状、纤维状及晶簇状等。通常为无色、乳白色，含杂质则染成各种颜色，有时具晕色，其中无色透明的晶体称冰洲石，玻璃光泽。摩氏硬度3，比重2.6-2.9，三组完全菱面体解理，故名方解石，性脆。遇冷稀盐酸剧烈起泡，放出CO2。 鉴定特征：菱面体完全解理，硬度不大，加稀盐酸剧烈起泡。｝。
