Product Overview

About Feldspar

Feldspar as a mineral and classify feldspars as mainly as albite, microcline, orthoclase and amortise. Sodium, potassium, and mixed feldspars can be further distinguished based on the type of alkali they contain. Feldspar is a common mineral raw material used as fluxing agents in Ceramic and Glass making and to some extent as a functional filler and extender in Paint, Plastics, Rubber and Adhesive Industries. Its dispensability, chemical inertness, constant pH, strong resistance to abrasion, low viscosity at high filler loading, fascinating refractive index, and resistance to icing are all advantages of feldspars.

Frequently Asked Questions

Important information about Feldspar, grades and applications.

Feldspar acts as a flux that lowers melting temperature of ceramic bodies and glazes, reducing energy costs while providing alumina for strength and durability.

Potash feldspar (Orthoclase) contains more K₂O and has a higher melting range. Soda feldspar (Albite) contains more Na₂O and melts at lower temperatures.

Low iron (

We offer feldspar in various mesh sizes from 100 to 400 mesh, tailored for specific ceramic and glass applications.
