About Feldspar
Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based upon feldspar content.
Quick Fact
The term feldspar encompasses a vast range of materials, including everyday objects we use, like: glass, insulation fiberglass, floor tiles, shower basins, tableware, etc
Extensive uses
Feldspar is widely used across industries. Like, fluxing agents in ceramic and glass applications, functional fillers in the paint, plastic, rubber and adhesive industries. .
Other End Uses
Other industries include: Paints, mild abrasives, urethane, welding electrodes (used in production of steel), latex foam, welding rod coating, and road aggregate.
Feldspar for
manufacturing Glass
Feldspars are primarily used in industrial applications for their alumina and alkali content.
Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs.
ceramic industries
Feldspar is the second most important ingredient in manufacturing Ceramics, after clay. Not having a strict melting point allows feldspar to melt gradually over a range of temperatures, facilitating melting of quartz and clays. And, through appropriate mixing, allows modulations of this important step of ceramic making.
Feldspars are used as fluxing agents to form a glassy phase at low temperatures and as a source of alkalies and alumina in glazes, helping improve the strength, toughness, and durability of the ceramic body, and cement the crystalline phase of other ingredients, softening, melting and wetting other batch constituents.
