Celsian
ID: celsian
BaAl2Si2O8 or BaO.Al2O3.2SiO2
Description
Celsian is a rare barium aluminosilicate member of the feldspar group, characterized by the chemical formula BaAl2Si2O8. Geologically, it typically forms within contact metamorphic environments rich in barium. Crystallographically, it belongs to the monoclinic system and presents as white, yellow, or transparent material in its natural state. Beyond its geological occurrence, synthetic barium aluminosilicate is utilized in ceramic engineering and restorative dentistry due to its specific refractory and chemical properties.
