200 Mesh Sodium Feldspar Powder

The versatile application of 200-mesh sodium feldspar powder across ceramics, glass fiber, and refractory materials underscores its importance in shaping the physical and thermal properties of a diverse range of end products within these industries.


Description of Sodium Feldspar Powder 

Sodium Feldspar of LSFeldspar is an important raw material for ceramic industry. Suitable product specifications are 100 mesh, 200 mesh and 325 mesh, Popular 200 mesh.
It can lower the glass transition temperature of the ceramic body, improve the brightness and clarity of the ceramic glaze, forms a uniform and stable glaze layer on ceramic surfaces and give ceramic products a durable and attractive surface smoothness.
Sodium feldspar has good compactibility, high heat resistance and low cost. It is widely used in the production of ceramic products such as sanitary ware, tableware, and ceramic tiles. It helps to improve the performance and cost-effectiveness of the final product, so it’s a popular choice for manufacturers.

Advantages of Sodium Feldspar Powder of LSFeldspar

• Si: Low Silicon and without free silicon, it's harmless to the body
• Al: High aluminum, has nepheline properties and good transparency
• Na: Na 11% around, fast burning at a lower temperature, save cost

200 Mesh Sodium Feldspar Powder in Sanitary Ware Production

Porosity Reduction: Sodium feldspar plays a crucial role in reducing the porosity of sanitary ware. Its fluxability allows for a dense and vitrified structure, makes the products less porous and leads to more water absorption resistance. This improves the hygiene and lifespan of sanitary ware items.
Resistance to Chemicals: Sodium feldspar enhances the resistance of sanitary ware to chemical agents, such as acids and detergents. This makes the products more suitable for everyday use in bathrooms and kitchens, as they come into contact with various cleaners.
Surface Finish: Soda feldspar contributes to achieving a smooth and lustrous surface finish on sanitary ware. Its presence in glazes or engobes ensures a glossy and visually appealing appearance, enhancing the overall aesthetic of bathroom fixtures and tiles.

200 Mesh Sodium Feldspar Powder in Ceramics Glazes and Engobes Production

Fluxing Agent: As a flux, Sodium feldspar lowers the melting point of the glaze or engobe composition. This promotes the fusion of other ingredients, ensuring a smooth, glassy surface when fired. Albite helps to create a durable and impermeable layer that protects the ceramic body while enhancing its appearance.
Color Enhancement: Soda feldspar enhances color development in glazes and engobes. Its high fluxing properties aid in the proper dispersion of colorants, resulting in vibrant and consistent colors on the ceramic surface. This allows for intricate designs and patterns to be achieved with precision.

200 Mesh Sodium Feldspar Powder in Pottery and Ceramics Production

Formation of clay bodies: Sodium feldspar mixed with clay used for pottery making. Its high fluxability ensures the fusion and vitrification of clay particles during firing, resulting in a robust and durable ceramic body.
Shape and Structure: Sodium feldspar contributes to the shaping and structuring of ceramic pieces. Its malleable and machinable characteristics make clay easier to shape and carve, allowing artists and potters to create intricate designs and achieve desired shapes.
Color Rending: Sodium feldspar contributes to the color rending of ceramics. Its presence in the clay body or glaze formulation influences the final color of the fired ceramic product. By carefully adjusting the amount of Soda feldspar, potters can obtain a range of colors, from earthy to vibrant hues.

200 Mesh Sodium Feldspar Powder used for Glass Fiber and Refractory Materials

Glass Fiber: The utilization of 200-mesh sodium feldspar powder proves instrumental. The powder is incorporated into the glass composition, contributing to the overall quality of the glass fibers. Its presence aids in achieving a homogeneous mixture, ensuring uniformity in the final product. This, in turn, enhances the tensile strength and durability of the glass fibers, making them suitable for a wide range of applications such as reinforcing materials in composites and insulation.
Refractory Materials: The specific characteristics of 200-mesh sodium feldspar powder are harnessed to impart desirable properties to the final product. The powder acts as a fluxing agent, reducing the melting point of the refractory material and enhancing its resistance to high temperatures. This makes it an essential component in the production of refractory bricks, crucibles, and other heat-resistant elements used in furnaces and kilns.
