Feldspar: Types, Uses, and Applications in Glass and Ceramics Industry, Slides of Geology

An overview of feldspar, its classification, uses, and applications in the glass and ceramics industry. It covers the different types of feldspar, including orthoclase, sanidine, microcline, albite, labradorite, oligoclase, bytwonite, anorthite, and andesine. The document also discusses the crystallographic properties of feldspar and its role as a bonding agent in the manufacture of bonded abrasives and as an important ingredient in the glass sand batch and the ceramics industry.

Feldspar is generally used for three purposes

In making the body composition of several

types of procelain, china and earthenware and

also in the preparation of glazes and enamel.

As an important ingredient in the glass sand

batch.

As a bonding agent in the manufacture of

bonded abrasives like wheels and discs of

garnet, corundum, emery etc.

The glass and ceramic industries are the major

consumers of feldspar and account for 95% of

the total consumption.
