Soda Feldspar refers to group of Aluminum Silicate of sodium. The chief use of Feldspar is in the Ceramic and Glass Industries. Smaller quantities are used in the manufacturing of Tiles, Whiteware, and Sanitaryware. Other uses of Feldspar include Catalysts, Acid resistant and Decorative Stone as a flux or binding agent in certain scanning Soaps and artificial teeth.
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.
SALIENT FEATURES
It acts as a flux
It is the main vitrifying agent in ceramic bodies
APPLICATIONS
Glass and Ceramic industries are the major consumers of feldspar and account for 95% of the total consumption.
Porcelain, china and earthenware
Preparation of Glazes and Enamel
Glass sand batch
Used as a bonding agent in the manufacture of bonded abrasives like wheels and discs of garnet, corundum, emery etc.
Potash Feldspar is a naturally occuring Potassium Alumino Silicate rock occurring in pegmatite bodies. Feldspar is used as a flux in ceramic and glass industries. It also adds strength to the body. Feldspar is a rare occurrence of extremely pure mineral free from mica. The chief impurities namely clay, and other foreign matter all occur as fine bodies below one mm.
It is used in many industries like Ceramics, Glass Industries, Pottery, Battery, lead-acid automotive, Beverage glass, Fluorescent light, Mirror Plate, ceramic, Polyvinylchloride (PVC) plastic pipe Sink, ceramic Television picture tube, Tile, Sanitary, bulb , tube light etc.
SALIENT FEATURES
Best for Ceramic & Sanitary Ware Manufacturing - Application in both Glaze (K2O > 11.5%) & Body (K2O >10.5%) â?? gives White Firing Colour.
Glass Grades â?? better fluxing from K2O > 10% (total alkalies > 13%), Alumina > 17% for strength, Low Iron Fe2O3 at < 0.5%.
High Potash K2O >11% for Flux coated Welding Electrodes.
APPLICATIONS
Wall & Floor Tiles â?? glazed Tiles, Vitrified Homogenous Tiles, Fast Firing, Third Firing.
Vitreous Porcelain â?? Tableware & Other Ceramic product.
Enameled Ceramics & Potteries.
Technical & Advanced Ceramics.
Vitrified Pipes & other Products.
Frits & Glaze.
The highest level of silica content in it makes it the most preferred mineral to be used in various industries and also for other personal uses. Among many other industrial uses, the most prominent uses of our Mica include:
It is used in paints as a pigment extender and also helps to brighten the tone of coloured pigments. It is vastly used as fillers, extenders along with providing smoother uniformity, improving workability and prevents cracking.
In the electrical industry the same as thermal insulation, and electrical insulators in electronic equipment
