Wholesale 100% Best Quality Petalite Powder Mineral (Lithium Ore Powder Petalite is unique for its thermal properties;

Petalite powder is a naturally occurring lithium aluminum silicate mineral (LiAlSi4O10) used primarily as a low-expansion filler in ceramics, glazes, and glass manufacturing. [1, 2]

Key Properties & Composition

• Chemical Formula: LiAlSi₄O₁₀ or Li₂O⋅Al₂O₃⋅8SiO₂
• Typical Lithia (Li₂O): ~3.5% to 4.86%
• Silica (SiO₂): ~76% to 78.5%
• Iron content: Very low (Fe₂O₃ around 0.01% to 0.2%), which allows for clear, transparent, or clean white glazes.
• Thermal Shock Resistance: Imparts extreme thermal durability; high-percentage bodies can take direct flame and water cooling without cracking due to near-zero linear thermal expansion. [1, 2, 3, 4, 5]

Primary Uses

• Ceramics & Pottery: Added to clay bodies to lower thermal expansion, prevent dunting (cracking during cooling), and act as an active secondary flux at both earthenware and stoneware temperatures. [1]
• Glazes: Supplies a clean source of lithium to glazes, though it can influence glaze fit and cause crazing if not balanced properly. [1, 2]
• Glass & Refractories: Functions as a high-silica, low-expansion raw material to improve the thermal stability of specialized glass and industrial refractory products. [1, 2]
