Hectorite
ID: hectorite
Na0:3(Mg; Li)3Si4O10(OH)2
Description
Hectorite is an infrequent, lithium-bearing phyllosilicate clay mineral characterized by a soft, greasy texture and a white appearance. Geologically derived from volcanic activity, this mineral belongs to the smectite group and possesses the chemical composition Na0.3(Mg,Li)3Si4O10(OH)2. Within the ceramics industry, hectorite is distinguished by its high plasticity and fine-grained structure, functioning as a valuable additive similar to bentonite. Its unique suspension properties and ability to modify rheology make it an effective component in ceramic body formulations and glaze compositions, where it acts as a stabilizer and binder.
