Minerals containing varying amounts of potassium, an important source of alumina in the ceramics manufacturing industries.
Potassium feldspar refers to a number of minerals in the feldspar group, and containing potassium: Orthoclase (endmember formula KAlSi3O8), an important tectosilicate mineral that forms igneous rock. Microcline, chemically the same as orthoclase, but with a different crystalline structure. 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 use of Feldspar is in the Ceramic and Glass Industries. In ceramic bodies, the main vitrifying (fluxing) agent is feldspar. Application Industries: Ceramics, Tiles and Sanitaryware Glazes Glass Industry Bonding agent for abrasives, wheels, discs, and other shapes. Dental ceramics.

Introduction: - Feldspar is primarily used in industrial applications for its alumina and alkali content. Feldspar is a naturally occurring anhydrous, inorganic, igneous rock. The fusibility of the mineral makes it useful raw material for many applications and the purity is the indication of better fusibility in the application.

Features Of Feldspar Feldspar is most common rock-forming mineral. It generally white or very light in colour. The feldspar refers to the group of Aluminium silicate of potassium, sodium and calcium. Among the numerous rocks in which they are present the feldspars are particularly abundant in igneous rocks. Applications Ceramics Sanitaryware Catalyst Decorative stone
Potassium feldspar, also known as K-Feldspar, is a common type of feldspar mineral that is composed of potassium, aluminium, and silica. It is one of the most abundant minerals in the Earth's crust and is found in many types of rocks, including granite, gneiss, and pegmatite, that has a wide range of industrial and scientific applications. Its unique properties make it a valuable resource in a variety of fields, from manufacturing to geology. For example, it is a key ingredient in the manufacture of glass and ceramics, where it is used as a flux to lower the melting point of the materials. It is also used as filler in plastics, rubber, and other materials. We, SRS Minerals are equipped to supply Good quality K-Feldspar, with Potassium content up to 12% in Lumps from 1-300mm size, and in powder form, if required.

What is Potash Feldspar? Potassium feldspar is a group of minerals which contain potassium and belong to the feldspar group. It is either colorless or very light in color. K-feldspar is another name for it. Furthermore, potassium feldspar is divided into two types: microcline and orthoclase. What are the specifications of Potash Feldspar?

Potash feldspars are more commonly used in ceramics, matte glazes, and they can create a crystallographic structure which helps them to be bright. Itâ??s also one of the most vital elements in ceramic glazes for medium and high temperatures. Potash feldspar can be used in industry to make it harder to disable the material surface. What are the other uses? In the paint, plastic, rubber, and adhesive industries, potash feldspar is used as a fluxing agent. Itâ??s also used as a concrete mixture. Enamel, scouring powder, and glass are all made with it. Potassium feldspar comes in a variety of colors and has the same economic value as a gold ring. Potash feldspars are significant as stone elements; they are found in alkali and acidic igneous rocks, especially syenites, stones, pegmatites, and gneisses in large quantities
