Nepheline
Tectosilicate mineral
Nepheline (from Ancient Greek νεφέλη (nephélē) 'cloud'), also called nephelite, is a rock-forming mineral in the feldspathoid group – a silica-undersaturated aluminosilicate (Na3KAl4Si4O16) that occurs in intrusive and volcanic rocks with low silica, and in their associated pegmatites. It is used in glass and ceramic manufacturing and other industries, and has been investigated as an ore of aluminium.
