高岭土由于具有颜色白、粒细、粘结力强、高的耐火度、以及优良的吸水性、可塑性、悬浮性、绝缘性、分散性和化学稳定性等特点。因此,被广泛应用于陶瓷、橡胶、造纸、耐火材料及化工部门,是当今工业很重要的非金属矿种之一。现今全世界已有60多个国家在生产高岭土,年产量近3000万吨,以年均5％的速度增长,世界市场年贸易量达650多万吨,预计2000年世界市场需求量将达4000万吨以上。我国现年产量约90万吨,市场需求量以5.1％速率增长,预计2000年总需求量为150万吨。可见国内外有广阔的市场前景。
Because of its color white kaolin, fine, strong adhesion, high refractoriness, and excellent water absorption, plasticity, suspension, insulation, dispersion and chemical stability and so on. Therefore, it is widely used in ceramics, rubber, paper making, refractory materials and chemical industry and is one of the most important non-metallic minerals in the industry today. Today, more than 60 countries around the world are producing kaolin, with an annual output of nearly 30 million tons, an average annual growth rate of 5%. The annual trade volume in the world market reaches more than 6.5 million tons. It is estimated that the world market demand in 2000 will reach 4,000 More than 10,000 tons. China’s current output is about 900,000 tons, the market demand growth rate of 5.1%, the total demand in 2000 is expected to 1.5 million tons. Shows a broad market prospects at home and abroad.
