Product Overview
The ultrafine crystalline silicon micropowder composite material is refined from high - purity natural white quartz through multiple precision processes. These processes include meticulous manual selection, high - purity water treatment, fine grinding, precise filtration, thorough drying, and strict screening, ensuring the excellent quality of the product. The material shows a pure white color, has extremely stable physical and chemical properties, and its particle size distribution is precisely controllable, demonstrating indispensable value in many high - tech fields.
Product Characteristics
- High Purity and Whiteness: The product has extremely high purity with minimal impurity content, presenting a pure white appearance, making it an ideal choice for application scenarios with strict requirements for color and purity.
- Excellent Insulating Performance: Due to its high purity and low impurity content, the material has excellent electrical insulating properties, which can effectively ensure the stable operation of electrical equipment and electronic products, and significantly improve their arc - resistance performance.
- Low Thermal Expansion Coefficient: It can reduce the linear expansion coefficient and shrinkage of the cured product, effectively eliminate internal stress, and greatly prevent the product from cracking during use, improving the structural stability and service life of the product.
- Good Chemical Stability: This characteristic enables it to remain stable in various complex chemical environments, providing reliable protection for products.
- Reasonable Particle Size Distribution: The particle gradation is scientifically reasonable. During use, it can effectively reduce and eliminate phenomena such as precipitation and stratification, ensuring the consistency and stability of product performance. At the same time, it can significantly enhance the tensile and compressive strength of the cured product, greatly improve wear resistance, and effectively increase the thermal conductivity of the cured product, enhancing flame - retardant performance.
- Good Wettability: After being treated with silane coupling agent, it shows good wettability to various resins, has excellent adsorption performance, is easy to disperse during mixing, and does not agglomerate, providing great convenience for the preparation of composite materials.
Application Areas
- Electronics and Electrical Industry: Widely used in potting materials, encapsulation materials, and molding compounds, it can effectively improve the insulation performance, thermal stability, and mechanical strength of electronic products, ensuring the reliable operation of electronic equipment in complex environments. At the same time, as an additive in engineering plastics and silicone rubber, it can significantly improve the material performance, meeting the high - performance material requirements of the electronics industry.
- Precision Ceramics and Casting: In the production of precision ceramics, it can optimize the microstructure of ceramics, improve the density, hardness, and wear resistance of ceramics, playing a key role in high - end ceramic products. In the casting field, it helps to improve the surface quality and internal structure of castings, and improve the accuracy and performance of castings.
- Anti - Corrosion Coatings and Paints: As a filler added to anti - corrosion coatings and paints, it can enhance the corrosion resistance, wear resistance, and insulation of the coating, extend the service life of the coating, and provide efficient protection for metals and other materials.
