Hot Sale Competitive Price Of High Quality Potassium Feldspar Powder for Ceramic Industry  

Introduction:

K-feldspar (KAlSi3O8) are commonly called orthoclase belongs to monoclinic system, specific gravity 2.56 ~ 2.59g/cm3, a theoretical composition of SiO2 64.7% Al2O3 18.4%, K2O 16.9%. It has a low melting point (1150 ± 20 ), melting interval for a long time and high melt viscosity, is widely used in ceramic billets, ceramic glazes, glass, porcelain, grinding materials and other industrial sectors and manufacturing potash fertilizer use. In addition to orthoclase, there are two variants of polymorph: permeability microcline feldspar and potassium feldspar. The former is also monoclinic, also known as orthoclase; the latter belong to triclinic system. Feldspar In addition to being outside the glass industrial raw materials (about the total amount of 50-60%), in the ceramic industry in the use accounted for 30% of the remainder used in chemical, glass flux, ceramic green body ingredients, ceramic glaze, enamel raw materials , abrasives, glass fiber, welding and other trades.

Mainly used in glass, ceramics, can also be used for the system to take potash fertilizer, better quality of K-feldspar glass, etc. for the manufacture of TV imaging. K-feldspar: K2O.Al2O3.6SiO2, which K2O 9.55%, Al2O3 16% or more, SiO2 70%, density of 2.56g/cm 3, Mohs hardness is 6, monoclinic, color is white, red, milky white.
