Feldspar is an aluminosilicate mineral of alkali metals or alkaline earth metals such as potassium, sodium, and calcium, also known as feldspar group minerals. Potassium feldspar (K2O · Al2O3 · 6SiO2), also known as orthoclase, belongs to the monoclinic crystal system and is usually flesh red...

The hardness of feldspar fluctuates between 6-6.5, the specific gravity fluctuates between 2-2.5, it is brittle, has high compressive strength, and has strong chemical stability to acid. The color of feldspar is mostly flesh red, but there are also gray and white brown. Sodium feldspar is...

Potassium feldspar is a potassium rich silicate mineral. He has the advantages of low melting point, long melting interval time, high melting viscosity, and low fluidity. Widely used in industrial sectors such as ceramic blanks and welding electrodes. Potassium feldspar powder is mainly used in t...

Ceramics are composed of two types of mineral materials: raw materials and glazes, collectively known as ceramic raw materials. The basic raw materials for the ceramic industry are natural minerals or rocks, which are abundant and widely distributed There are various raw material compositions in...
