典型的球土是一种细粒混合物,70％为无序高岭石,还含有伊利石、石英、蒙脱石、绿泥石和少量碳酸盐矿物。球土的颜色主要由所含的有机质决定。球土由于具有很高的塑性、干燥强度和很宽的玻璃化范围而广泛用于陶瓷工业。球土的碳酸盐成分在焙烧时大部分烧尽,形成白色或近白色的产品。世界最优质的球土矿床位于捷克斯洛伐克、美国的肯塔基—田纳西地区,以及英国西南部。塑性粘土主要
A typical ball of earth is a fine-grained mix of 70% disordered kaolinite and illite, quartz, montmorillonite, chlorite and small amounts of carbonate minerals. The color of the earth is dominated by the organic matter it contains. Ball clay is widely used in the ceramic industry due to its high plasticity, dry strength and wide glassy range. The carbonate content of the earth’s earth is mostly burnt out during firing, forming a white or nearly white product. The world’s highest quality dome deposits are located in Czechoslovakia, the Kentucky-Tennessee region of the United States and south-west England. Plastic clay mainly
