Lingshou Yijia Mining specializing in the production of feldspar, feldspar, feldspar family rock cited the general term, it is a class of calcium, sodium, and potassium aluminum silicate mineral. The most common mineral in the Earth's crust, the ratio reached 60%, can occur in igneous, metamorphic, and sedimentary rocks. Feldspar is the main mineral components of almost all igneous rocks, of great significance for the classification of the rock. Feldspar hardness fluctuations in 6-6.5, the proportion of fluctuations in the 2-2.5, is brittle, has a higher compressive strength, strong chemical stability of the acid. K-feldspar color of red meat. Albite, white, light yellow, anorthite as a white or light gray. Feldspar common specifications :20-40 mesh ,40-80 mesh, 100 mesh, 120 mesh, 200 mesh, 325 mesh.

 K-feldspar is a potassium-rich silicate minerals. He has a low melting point and melting interval is long, high melt viscosity, the mobility of small advantages. Widely used in the ceramic billet, welding and other industrial sectors. <0.02% of feldspar, titanium dioxide, burning vector 0.54, hardness fluctuations in 6-6.5, is brittle, has a higher compressive strength, strong chemical stability of the acid, the main purposes are: manufacture of flat glass, alkaline glass, glassware, potash, abrasive, abrasive, ceramic fuel, high-voltage porcelain. 
 Feldspar products: potassium feldspar powder, sodium feldspar ore, potash feldspar ore Albite.
