Introduce:

1: high-purity silicon powder:
High-purity silicon powder is gray to dark gray powder, finer particle size of the darker color. Manufacturing high-purity silicon powder in high-purity silicon block by high-purity silicon block by crushing, grinding, screening first-class series of craft made by iron and other metals pollution in the crushing and grinding process is inevitable, the silicon block is very hard, even if very pure silicon block after processing may also be very pure silica fume. The company after years of study, developed a set of control after the crushing process to avoid the contamination of metals and other impurities and to deal with the purification process route, there is a firm guarantee of the quality of the finished product of high purity silicon powder.
High purity silicon powder Specification: 1:3 N-5N 2: granular (50-300 mesh), ultra-powder (mesh 1000-3000)
The use of high-purity silicon powder is widely used in the manufacture of advanced aluminum alloys, advanced refractories, high-performance ceramics, high-strength material (silicon nitride, silicon carbide), anti-corrosion coatings, high-performance alloy materials (silicon, titanium, silicon aluminum), and synthetic organic silicon (siloxane, silane), as the conversion of solar thermal solar thermal absorbers. Aviation, defense, automotive, ceramics, chemical industry, the photovoltaic industry, diamond tools, electronics industry, a wide range of applications.

2: target: 5N silicon, 5N Si-Al-chip
1:5 N silicon: gray or silver-white, irregular sheets and bands, with a metallic luster. Processed into high-purity silicon block by a special process. Specifications: Wafer ring piece, side piece. The product is suitable for manufacturing high-end sputtering targets.
2:5 N the Aluminosilicate piece: silver-white metallic luster, melting from high purity silicon by high purity aluminum, high purity, excellent quality, manufacturing advanced sputtering targets, but also the middle of the rule of aluminum alloy alloy specifications: Si / Al ratio 30/70 50/50 70/30.

3: 5N-6N solar Polysilicon
1:5 N solar polysilicon (boron, phosphorus impurities is less than 1 ppm) can be used for the use of admixtures.
2:6 N solar polysilicon (boron, phosphorus impurities is less than 0.2ppm) can be used directly in the solar single crystal, polycrystalline production.
