Potash Feldspar (Powder and Lumps)

Non Metallic Minerals - Potash Feldspar
The name of “Feldspar” refers to group of Aluminum Silicate of potassium, sodium and calcium. The chief use of Feldspar is in the Ceramic and Glass Industries. Smaller quantities are used in the manufacturing of Tiles, Whiteware, and Sanitary ware. Other uses of Feldspar include Catalysts, Acid resistant and Decorative Stone as a flux or binding agent in certain scanning Soaps and artificial teeth.
Potash (Potassium) Feldspar
In ceramic bodies, the vitrifying (fluxing) agent is feldspar. The majority of white ware bodies contain good proportions of feldspar. It acts as a flux. In the ceramic industry, the flux is defined as that proportion of the body which develops glass phase. This is provided mostly by feldspar. The amount of flux in a ceramic body should be only in such a proportion as to develop the desired amount of vitrification. If excess of flux is added, the fired body becomes very glassy and consequently, brittle.
The glass and ceramic industries are the major consumers of feldspar and account for 95% of the total consumption.
Potash Feldspar is generally used for three purposes
In making the body composition of several types of porcelain, 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 manufacturer of bonded abrasives like wheels and discs of garnet , corundum, emery etc.
