在不同的水热条件下制备了球形和片状高岭石晶体。球型高岭石主要在高固水比（1/4）和低温（150°~ 200°C）条件下生产。在中等固水比（1/256-1/16）和高温条件下，实验产物中以板状高岭石为主。在所有实验温度（180°-220°C）下，薄水铝石在低固水比（1/4096）下占主导地位。结果表明，高过饱和度有利于球形高岭石的生长，而低过饱和度有利于板状高岭石的生长。
Spherical and platy kaolinite crystals were prepared under several hydrothermal conditions. Spherical kaolinite was produced mainly at high solid/water ratio (1/4) and at low temperatures (150°-200°C). Platy kaolinite predominated in products from experiments with intermediate solid/water ratios (1/256-1/16) and at high temperatures. Boehmite predominated at low solid/water ratios (1/4096) at all experimental temperatures (180°-220°C). The results indicate that the growth of the spherical kaolinite was favored at high degrees of supersaturation, whereas the growth of the platy kaolinite was favored at relatively low degrees of supersaturation.
