高岭土,又称高岭石粘土,俗称“瓷土”。主要是由高岭石和埃洛石所组成。依其成矿母岩和成矿条件不同,除高岭土外,还含石英、长石、云母、蒙脱石、伊利石、黄铁矿、碳酸盐及有机质等。呈白、黄、灰、玫瑰等色,致密状、用砾状或土块状。是在湿热气候条件下由铝硅酸盐类矿物(主要是长石)经长期风化而成,也可由热液蚀变或表生沉积作用形成。这是一种用途广、使用价值大、经济效益好的粘土矿。由于高岭石具有很强的分散性、可塑性、烧结性、耐火性,还有良好的绝缘性、离子交换性及化学稳定性,因此,它的应用范围涉及工业部门的许多领域,成为国民经济的重要矿产资源之一。随着工业和科学技术的迅速发展,高岭土的应用早已超出陶瓷、搪瓷和耐火材料的领域,它在造纸、橡胶、油漆、石油、化工、建材、电子和尖端等领域也都得到广泛应用。 Kaolin, also known as kaolinite clay, commonly known as “clay”. It is mainly composed of kaolinite and halloysite. According to their metallogenic rock and metallogenic conditions are different, in addition to kaolin, also contains quartz, feldspar, mica, montmorillonite, illite, pyrite, carbonate and organic matter. Was white, yellow, gray, rose and other colors, dense, with gravel or soil block. It is formed by long-term weathering of aluminosilicate minerals (mainly feldspar) under wet and hot climatic conditions and also by hydrothermal alteration or epigenetic deposition. This is a wide range of uses, the use of large, cost-effective clay mine. Due to its strong dispersibility, plasticity, sinterability, fire resistance, good insulation, ion exchange and chemical stability, kaolinite has applications in many fields of the industrial sector and has become a national economy One of the important mineral resources. With the rapid development of industry and science and technology, the application of kaolin has long been beyond the field of ceramics, enamel and refractory materials. It is also widely used in the fields of papermaking, rubber, paint, petroleum, chemical industry, building materials, electronics and cutting-edge.
