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 manyapplications and the purity is the indication of better fusibility in the application.

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.

Feldspar are chemically alumino-silicates. There are several types of feldspar available in the state of Rajasthan (India): Most deposits offer sodium feldspar, potassium feldspar and mixed feldspar.
The fusibility of the mineral make it useful raw material for many application and the purity is the indication of better fusibility in the application. The geological context specific to each deposit gives the feldspar a variety of physical and chemical properties, thus providing products for a full-range of ceramic and glass making applications.
At mines the deposits are blasted to break up the rock and make it accessible to the diggers and loaders. The material after breaking up are manually sorted to prepare feed stocks and than each lot is tested with a view to providing the process plant with a constant homogeneous supply that is appropriate for the application purposes. The selected material is than transported to the users.
The remaining product (R/O) is directly sold in the form of sand to glass manufacturers or ground for ceramic markets.
The processing techniques at PEEKAY MINERALS ensures consistent quality freedom from impurities at pocket friendly costs.

What are the Uses in Ceramics?
Soda feldspar is an important element in the ceramic industry. It is used as a fluxing agent to create a glassy phase that quickens the melting of ceramic tiles. It is used in the creation of clay bodies and glazes. They primarily give wastes to the compositions in all situations, but they also offer extra alumina and silica. They have a higher melting point and their delivery of the soda feldspar is more liquid and less dense.
What are the Applications in others?
Soda Feldspar is a popular raw material used in ceramics, but it is also utilized as a filler and extender in paint, plastics, glassmaking, and rubber to some extent. It improves product hardness, durability, and chemical stability in glassmaking.
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.

How is it used in the ceramic industry?
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
