中文摘要:宜昌透辉石矿床产于前震旦系崆岭群小渔村组含透辉石大理岩中，规模大，矿体呈层状产出，层位稳定，开采条件优越。矿床由8个矿体组成，品位富(矿体平均含矿率为66.16—80.73％，厚5—90m。矿石经X射线衍射和差热等分析，证实矿物成分主要为透辉石，含量为90一94％。工业试验表明，透辉石是一种低温、快烧、高节能新型陶瓷原料，产品各项指标均达国家标准。
Abstract:The Yichang diopside deposit occurs in diopside-bearing marble of Xiaoyucun Formation of pre-Sinian Kongling Group and is composed of eight orebodies, being large in size. Layered in form, the orebodies have stable stratigraphic horizon and rich grade(average ore ratio of the orebodies being 66.16—80.73％)．With the thickness of 5-90m and superior mining condition, the deposit is an ideal large size one which is near in distance, rich in grade, shallow in, depth and easy in mining. The X-ray diffraction and differential thermal analyses of the ore demonstrate that diopside is the main mineral component, whose content is up to 90-94％. The diopside is mainly characterized by prismatic and platy crystal which form prismatic aggregates. The single crystals are usually 5-50cm in length, with rare giant crystals whose length is over 50cm. Industrial experimentation shows that the glazed brick made of diopside has better technological properties than ordinary clay glazed brick and is superior to glazed brick of other compositions in such aspects as sintering temperature and cycle, qualification rate, rate of first class product,absorption rate and contraction rate. It is therefore a low temperature, fast burning and effective energy-saving new type porcelain material, with various quality indexes of its products all reaching national standard.
