High purity graphite power

Vetek Semiconudctor provide high purity graphite powder with high purity and customized particle size for different industries including semiconductor applications.

Graphite silty soft, black gray; Greasy, can pollute the paper. The hardness is 1 ~ 2, and the hardness can be increased to 3 ~ 5 along the vertical direction with the increase of impurities. The specific gravity is 1.9 to 2.3. Under the condition of isolation of oxygen, its melting point is above 3000 ° C, which is one of the high temperature resistant minerals.

Vetek semiconductor’s high purity graphite powder is a high quality product with a purity of up to 5ppm. We strictly control the impurity content of our materials to ensure that they meet the highest industry standards. Our graphite powder can be customized according to particle morphology, allowing for greater flexibility in use. It is mainly used for the synthesis of silicon carbide powder and diamond synthesis. The high purity and precise particle size distribution of our products make them ideal for customers in the semiconductor, electronics and high-tech industries.

Vetek semiconductor has always provided fine powders with its extremely high purity and excellent high crystallinity, which plays a role in multiple industries, especially the semiconductor industry. Offering a wide range from 1 to 100 micron grades, our powder products include 99.999% ultra-high purity to meet customers' basic applications in all fields.

Fine powder is produced through an integrated production system from raw material processing to finished product, taking full advantage of the latest cutting-edge production equipment and our unique high-level processing technology. Under unified manufacturing management, raw materials are crushed to levels of 1 to 100 microns, depending on the application, through ultrafine grinding and grading equipment. Through the sorting process, raw materials are made into sophisticated products.

High purity graphite powder has good chemical stability. With good corrosion resistance, good thermal conductivity and low permeability, it is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, pumps and other equipment.

Due to the small coefficient of thermal expansion of graphite powder, and thermal shock changes can occur, it is usually used in crystal growth furnaces, such as monocrystalline silicon, regional refining containers, bracket fixtures, induction heaters, etc., are processed from high-purity graphite. In addition, graphite can also be used as vacuum smelting graphite insulation board and base, high temperature furnace tube, rod, plate, grid and other components.
