Plain Feldspar Lumps, Feature : Antibacterial, Durable

We are a reputed Manufacturer, Exporter & Supplier of Feldspar Lumps. The Feldspar Lumps offered by us are clusters of rock that form tectosilicate mineral. Feldspar is found in several metamorphic and sedimentary rocks. Depending at the predominant alkali metal element (the flux), Feldspar Lumps are divided into potash (potassium) or soda (sodium) feldspars. Feldspar Lumps are the naturally occurring minerals that are commonly used in making clay bodies and glazes. The purpose of using Feldspar Lumps is to provide fluxes to the formulations as well as to add extra alumina (Al₂O₃) and silica (SiO₂). Lithium feldspars are the aluminosilicates that contain lithium as the fluxing element. Our company specializes in offering White Feldspar, Common Feldspar Rock, etc., to the clients at competitive prices.

Industrial Applications

• Glass : 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.
  Ceramics : In the manufacture of ceramics, feldspar is the second most important ingredient after clay. Feldspar does not have a strict melting point, since it melts gradually over a range of temperatures. This greatly facilitates the 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. They 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.
• Fillers : Feldspars also are used as fillers and extenders in applications such as paints, plastics and rubber. Beneficial properties of feldspars include good dispersability, high chemical inertness, stable pH, high resistance to abrasion, low viscosity at high filler loading, interesting refractive index and resistance to frosting. The products used in such applications are generally fine-milled grades.
• Enamel frits and glazes : Feldspar assists the enamel composition, assuring the absence of defects and the neatness of the end product: e.g. enamel frits, ceramic glazes, ceramic tile glazes, sanitaryware, tableware, electrical porcelain and giftware.
• And many other end-uses : paint, mild abrasives, urethane, welding electrodes (production of steel), latex foam, the welding of rod coating, and road aggregate.
