补充资料:硅藻土
硅藻土 diatomite 以蛋白石为主要矿物组分的硅质生物沉积岩。主要由硅藻的遗骸组成。硅藻在生长繁衍的过程中,吸取水中胶态的二氧化硅,形成由蛋白石构成的硅藻壳,而硅藻土即由80%~90%甚至90%以上的硅藻壳组成。此外,含有少量的粘土矿物、铁的氧化物和炭有机质等。硅藻土的外形为块状或页岩状,颜色有白色、灰绿色、暗绿色及蓝灰色等,硅藻含量愈大,杂质愈少,则颜色愈白,质愈轻,其比重一般为0.4~0.9。由于硅藻体具有很多的壳体孔洞,使硅藻土具多孔质构造,孔隙度达90%~92%,吸水性强。硅藻颗粒细小约为0.001~0.5毫米,使硅藻土细腻、润滑。硅藻土不溶于HCl、H2SO4和HNO3,但溶于HF和KOH。由于硅藻土具有很多独特的物化性能,因而在工业上用途较广,它是理想的过滤介质,化工催化剂载体,优质隔热保温材料,陶瓷原料,建筑材料以及塑料、橡胶、油漆、制皂、制药等工业的优质填料。
