Description of Sodium Feldspar Powder 

325 mesh sodium feldspar powder plays a key role in two major fields: ceramic glaze and glass fiber. In ceramic glaze, as a stable sodium source, it can significantly reduce the firing temperature and improve the flatness and glossiness of the glaze surface. In glass fiber production, the high purity of this material (Na2O content 11%) helps to form high-strength fibers, making it an ideal network modifier. This dual application performance makes it show irreplaceable technical and economic value in improving the aesthetic quality of ceramics and enhancing the mechanical properties of composite materials.

325 Mesh Sodium Feldspar in the Glass Fiber Industry

Optimized Melting Characteristics: Sodium feldspar contributes to the reduction of the glass transition temperature, enhancing the overall melting properties. This optimization facilitates a more efficient and controlled melting process during glass fiber production.
Improved Flow Properties: The finely ground nature of the 325 mesh powder enhances the flow characteristics of the glass melt. This improvement is crucial for the drawing and forming stages of fiber production, ensuring uniformity and consistency in the resulting glass fibers.
Enhanced Fiber Strength and Durability: The addition of sodium feldspar contributes to the overall strength and durability of glass fibers. This is particularly valuable in applications where robust and resilient fibers are essential, such as in construction materials or components requiring high tensile strength.
Excellent Heat Resistance: Glass fibers produced with sodium feldspar exhibit superior heat resistance. This characteristic is advantageous in applications where exposure to elevated temperatures is common, ensuring that the fibers maintain their structural integrity and performance.

325 Mesh Sodium Feldspar Powder used in Ceramic Glaze

Control of glaze system stability: As a high-quality flux raw material, 325 mesh sodium feldspar powder can significantly improve the stability of glaze formula with its monoclinic crystal structure and specific particle size distribution. Its uniform particle grading ensures that the glaze slurry has ideal rheological properties and achieves highly uniform dispersion of solid phase components, thereby ensuring the batch stability of glaze chemical composition.
Optimization of glaze film-forming performance: The sodium feldspar powder of this particle size specification can form an ideal particle packing density during the glaze layer sintering process through precise particle size control. Its low thermal expansion characteristics effectively match the requirements of body glaze combination, promote the formation of defect-free glaze layer, and significantly improve the gloss and mechanical strength of the glaze.
Visual and Functional Properties: Incorporating 325-mesh sodium feldspar powder into ceramic glazes significantly influences the visual and functional properties of the final product. The fine powder contributes to the glaze's texture, color, and overall appearance. Moreover, its presence enhances the durability and performance of the glazed ceramic, making it more resilient and suitable for various applications.
