Product area:

Customized products to meet the actual needs of users, such as high purity quartz sand, silicon powder, spherical silicon powder so on.

We have professional technical personnel, professional equipment production workshop for customers to produce stable performance products.

1, high purity quartz sand (Fine Silica Powder) generally refers to quartz particles with SiO2 content higher than 99.99%. The technical conditions of our hospital can be more than 99.995%. Characteristics: high temperature resistance, low thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect unique optical effect. Quartz glass made of high purity quartz sand, its temperature resistance is as high as 1100-1200℃, 800℃ higher than ordinary glass, melting point platinum (platinum) melting point similar. The thermal expansion rate is very small, the average thermal expansion coefficient α=5.4 ×10-7, equivalent to 1/6 of ceramic, 1/20 of ordinary glass. Quartz glass has good spectral characteristics, can pass through infrared, ultraviolet. Quartz glass is a good acid - resistant material, equivalent to acid - resistant ceramics 30 times. It's 150 times stronger than stainless steel. Quartz glass is a better electrical insulation material, its resistance value is equivalent to 10000 times of ordinary glass, insulation strength of 250KV/cm, vacuum degree up to 10-6Pa.

2, high purity ultrafine quartz powder: Jingrui's current technology can reach the median diameter D50 control in 3-5μm, the total content of impurities control in 50ppm, belongs to the domestic top level, the international advanced!

3, spherical silicon powder: It is made by high frequency plasma method using Jingrui's technology. It has the characteristics of high temperature resistance, high insulation, corrosion resistance, good fluidity, small thermal expansion coefficient, small concentrated stress, small friction coefficient small thermal conductivity. It can be replaced by other materials in the epoxy resin molding material industry. It is widely used in aviation, aerospace, fine chemical industry, large area electronic substrate, erasable optical disc, special ceramics other fields.
