an aluminosilicate mineral group of 21 kaolinite

As nouns the difference between aluminosilicate and kaolinite is that aluminosilicate is inorganic chemistry any of many silicate minerals such as feldspar and zeolite in which a proportion of the si 4 ions are replaced by al 3 the excess negative charge being balanced by extra sodium potassium or calcium ions while kaolinite is mineralogy a common hydrous aluminosilicate mineral
