用途

Application

High Purity: The silica pebbles produced by Dalian Xingya Silica Processing Plant have a high silicon dioxide (SiO₂) content of over 99%, ensuring no contamination of the raw materials during grinding.

Excellent Wear Resistance: With high hardness (Mohs hardness 8) and chemical stability, our high-silica pebbles exhibit outstanding wear resistance under various conditions, making them ideal for high-intensity grinding applications.

Uniform Particle Size: Through precise processing and secondary screening, our high-silica pebbles achieve a consistent particle size distribution, meeting the specific requirements of different industrial applications.

High Silica, Low Iron: Xingya Silica products feature high silica and low iron content. During grinding, the wear mainly contributes SiO₂, preventing contamination of the raw materials and making the pebbles suitable for a wide range of grinding applications.

Applications: Based on these characteristics, Xingya silica pebbles and grinding media are widely used for crushing and grinding raw materials in the following industries:

• Ceramics: Silicon dioxide is the primary chemical component of ceramic bodies, directly influencing thermal stability, chemical stability, hardness, and mechanical strength. High SiO₂ content enhances sintering temperature, wear resistance, hardness, and thermal expansion performance of ceramic products.

• Glass: Silicon dioxide forms the “framework” of glass, determining its physical and chemical properties. It increases the viscosity of molten glass, reduces crystallization tendency, and improves chemical and thermal stability. Its high melting and boiling points provide excellent high-temperature resistance, while its insolubility in water and inertness to most acids ensures superior corrosion resistance.

• Chemical Industry: In chemicals, high-silica micro-powder serves as a filler in rubber, plastics, coatings, and other products, enhancing processing and mechanical performance. Xingya silica pebbles’ high silica content makes them ideal for these applications.

• Electronics: Silicon dioxide is a key raw material for semiconductor production and high-performance electronic components. Xingya silica pebbles can serve as grinding media to ensure the quality of products during the manufacturing of semiconductors and electronic components.
