Feldspar
Potassium feldspar and Sodium feldspar
Feldspar is an aluminosilicate mineral containing calcium, sodium, and potassium.Feldspar rich in potassium or sodium is mainly used in ceramic industry, glass industry and enamel industry.
Potassium feldspar is a potassium-rich silicate mineral with the advantages of low melting point, long melting interval and high melt viscosity. It is one of the main raw materials for the glass and ceramic industries, as well as the main raw materials for artificial grindstones, welding rods and potash fertilizers. It can be widely used in industrial fields such as processing and extracting potash fertilizers, and is an important energy-saving mineral raw material to replace alkali.
Albite is a common sodium-containing aluminosilicate rock-forming mineral. During the heating process of albite, its theoretical melting point is 1100°C. The melting point of natural albite ore varies with its chemical composition. Sodium feldspar can be used to produce polished tiles, exterior wall tiles, floor tiles, etc.Feldspar

Application
Nothing is more important than the trusted relationships we have with customers.Our growth is based on mutual success.
Feldspar Main Applications:
(1) ceramic body ingredients:
in the firing of feldspar can be barren of raw materials, reduce green body drying shrinkage and deformation, improve the drying performance, shorten the drying time.
(2) glass flux:
feldspar is one of the main ingredients of glass mixture. Feldspar containing Al2O3 high, low iron content and than alumina fusible, not only the melting temperature is low and wide melting range, is mainly used to improve the content of alumina glass batching, reduce the melting temperatures of glass production and increase the content of alkali, in order to reduce alkali dosage.
(3)ceramic glaze:
ceramic glaze is mainly composed of feldspar, quartz and clay raw materials prepared, including feldspar content of up to 10 - 35%. In the ceramic industry (blank and glaze) is mainly used potassium feldspar.
(4) enamel raw materials:
the main use of feldspar and other mineral raw materials blending method Lang. The content of feldspar is usually 20 - 30%.
(5) other: potassium feldspar can be used as raw material for extracting potash.- Contact Us
