The name of “Feldspar” refers to group of Aluminum Silicate of potassium, sodium and calcium.
Rock n Clay is one of the leading manufacturer and exporter of superior quality of wide range of Sodium Feldspar.
By using latest technology and team of highly qualified professionals, we produce these feldspars in
various specifications and range, that too in a very economical and eco-friendly manner.
Applications: Feldspar is generally used in Ceramics, Glass, and Electrodes. The glass and ceramic
industries are the major consumers of feldspar and account for 95% of the total consumption. Other uses
of Feldspar include Catalysts, Acid resistant and Decorative Stone as a flux or binding agent in certain
scanning Soaps and artificial teeth.
Feldspar is generally used in making the body composition of several types of procelain, china and
earthenware and also in the preparation of glazes and enamel. It is also used as an important ingredient
in the glass sand batch. Used as a bonding agent in the manufacture of bonded abrasives like wheels
and discs of garnet, corundum, emery etc.
In ceramic bodies, the main 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 portion 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.
