我国煤系高岭土的开发利用现状及发展趋势

煤系高岭土是一种宝贵的自然资源和重要的非金属矿产。它具有很多可以利用的性质，如耐火性、电绝缘性、化学稳定性、分散性等，开发后可用于造纸、橡胶、油漆、化工、建材、冶金、陶瓷、玻璃、电瓷、石油等行业，是许多工业部门不可缺少的矿物原料。但是煤系高岭土在开发中存在许多问题，如资源开采利用率低，规模小，技术落后，生产率低，缺乏统一规划，基础科研投入少，产品品种少，档次低。本文将介绍煤系高岭土的技术发展及趋势。

Present Situation on Development and Utilization of Coal Formation Kleit in China and its Developing Trend

The coal formation kleit is not only a kind of precious natural resource, but as well an important nonmetal mineral, which has a variety of properties to be used, for example, fire resistance, electrical insolation, chemical stability, dispersity, etc.. It is a kind of indispensable raw mineral materials for many industries, such as paper, rubber, paint, chemicals, building materials, metallargy, ceramics, glass, electroeeramics, petroleum, etc.. However, there are a lot of problems existed in the development of kleit, for instance, low resource availability, small scale, lag in technology, low productivity, lack of unified planning, deficiencies in investments for basic scientific research, less product variety and low grade. The technological development and the trend for the coal formation kleit will be introduced.
