Lithium Feldspar
LiAlSi₂O₆ / LiAlSi₄O₁₀
Lithium-bearing feldspathoid minerals supplied for low-expansion glass ceramics, fast-fire glazes, and specialty porcelain.
Overview
Lithium feldspar encompasses spodumene, petalite, and lepidolite minerals that introduce Li₂O – the most powerful ceramic flux – into ceramic and glass systems. Lithia significantly reduces melting temperatures and thermal expansion, making these minerals commercially critical in fast-fire tile glazes, low-expansion glass ceramics, and specialty porcelain formulations.
