矽卡岩型金尾矿制作工艺陶瓷坯体材料的研究

利用现代技术手段，系统观测湖北某矽卡岩型金尾矿的物相组成、化学组成、颗粒级配等特征.针对其特征，选取陶土弥补缺陷.按照成陶要求设计的坯料与水混练制成生坯，在氧化气氛中，经980~1000℃，15h烧成坯体材料.结果表明:生坯经过烧制生成了钙长石等稳定的新矿物相，烧成的坯体材料内部结构致密，吸水率为746%，莫氏硬度为55~6，满足工艺陶瓷坯体的性能要求.所选矽卡岩型金尾矿制作工艺陶瓷坯体具有可行性.

Research of Making Skarn Gold Mine Tailings into Art Pottery Body Material

By modern technology，phase composition， chemical constitution and grain composition of a skarn gold mine tailing from Hubei Province were systematically tested. Remedying the defect of tailings used pottery clay according to its composition. Mixing water and raw material for green bodies and then firing the green bodies into the pottery bodies was designed under oxidizing atmosphere through 15hours with the firing temperature of 980~1000℃. The results showed that some new kinds of mineral facies， such as calcium feldspar， appear in pottery bodies and the pottery bodies meet the performance requirements of art pottery bodies because of their close grained internal structure， 746% water absorption and 55~6Mohs hardness. It can be proved that skarn gold mine tailings are feasible for art pottery body materials making.
