毒重石分子式：BaCO3CAS号：性质：又称碳酸钡矿，简称碳钡矿。是除重晶石之外的另一含钡矿物。含氧化钡77.7％，常含少量锶和钙。斜方晶系，晶体常呈双锥状、短柱状、板状；集合体常呈粒状、球状、肾状等。无色、白色，常被杂质染成浅灰、浅黄、绿、褐等色。玻璃光泽。硬度3～3.5，密度4.29g/cm3。性脆。有毒!可耐高温，常压下1400℃不分解，约在1450℃分解失去二氧化碳。不溶于冷水，极难溶于沸水，微溶于含有二氧化碳的水，溶于盐酸放出二氧化碳。常见于低温热液矿床中，与重晶石、方解石、白云石等共生。用作石油和天然气钻井泥浆的加重剂，是制造各种钡化合物的矿物原料。用于制颜料、焰火、光学玻璃、杀鼠药、陶器、瓷器。还可用作填料和水澄清剂等。
