Elevating Quality in Ceramics and Glass Craftsmanship
Sodium Feldspar Powder
At Rahul Overseas, we offer premium-quality Sodium Feldspar Powder (MALDIVES), a vital raw material for industries such as ceramics, glass manufacturing, and paint production.
Our Sodium Feldspar Powder (MALDIVES) is known for its high alumina content and low melting point, making it ideal for enhancing the strength, durability, and finish of ceramic and glass products.
Its excellent fluxing properties aid in reducing the firing temperature during the manufacturing process, improving energy efficiency and product quality.
Potash feldspars are used primarily in clay bodies to promote vitrification, which is the process of turning the part of the body into glass. It melts at a slightly higher temperature (1200°C) than soda spar.
Sodium feldspars are most commonly used in glazes. For your clay body, potassium feldspar is the king.
In MALDIVES most of the products we use on a daily basis are made with feldspar: glass for drinking, glass for protection, fiberglass for insulation, the floor tiles and shower basins in our bathrooms, and the tableware from which we eat.
Product Description
- Potassium Feldspar Lumps: The name Feldspar refers to a group of aluminum silicates containing potassium, sodium, and calcium.
The chief use of Feldspar is in the ceramic tiles, sanitary ware, pottery, insulators, ceramic frit, and glass industries.
Smaller quantities are used in other industries.
Potassium feldspar melts at around 1200 °C (higher than soda feldspar), producing a more viscous melt than sodium feldspar.
It can also produce a crystalline phase (leucite) that contributes to opacity.
Thus, in industry, potash feldspars are often used more for matte glazes, while soda feldspar is used for glossy glazes.
Potash feldspar, or potassium feldspar, find applications as low-cost fluxing agent in the production of ceramic items, i.e. compounding of tiles, sanitary wares, tableware, insulation, and glazes.
Potassium feldspar / Potash feldspar is used in glass-production, where it supplies the aluminum which enhances the strength and transparency of hollow glass, flat glass and glass wool.
Potash feldspar or Potassium feldspar, is used as filler in paints, plasters, insulation, etc. - Enamel frits and glazes: Feldspar assists the enamel composition, assuring the absence of defects and the neatness of the end product: e.g. enamel frit, ceramic glazes, ceramic tile glazes, sanitary ware, tableware, electrical porcelain and gift ware. Potash feldspar find applications in paint, mild abrasives, urethane, welding electrodes (for the production of steel), latex foam, the welding rod coating, & road aggregate.
