2025-9-24

Feldspar powder is one kind of aluminosilicate mineral which contains potassium, sodium, calcium, barium and other alkali metal or alkaline earth metal「Mohs hardness 6-6.5, specific gravity 2.5-2.7, melting point 1100-1300 ℃」. Feldspar is one of the most common rock-forming minerals with crystal structure, possesses higher compressive strength, good chemical stability. The products are widely used in marine engineering, shipbuilding, heavy industry anti-corrosion, wood, decoration, powder coatings and other fields.

▎Product features
