The establishment of four roller black silicon carbide production line, the product output can reach 70,000 tons per year.Today, 35,000 tons of production lines and supporting deep processing workshops have been put into production.
Production of silicon carbide Silicon carbide can be found in the mineral moissanite, but it is rarely found in nature. So, it is synthetically produced by a synthesising technique called the Acheson method, named after its inventor, Edward G. Acheson.
2017/1/25· Compared to silicon or gallium arsenide, the Silicon carbide (SiC) is a rather young base material in the semiconductor industry but its origins date back to the end of the 19th century. In 1891, Edward Acheson developed a method for producing crystalline SiC as an abrasive material — a method still in use today.

Production of Silicon Carbide SiC powders are produced predominantly via the traditional Acheson method where a reaction mixture of green petroleum coke and sand is heated to 2500°C using two large graphite electrodes.
Specifically provided is a silicon carbide powder for the production of a silicon carbide single crystal, which has an average particle diameter of 100-700 μm (inclusive) and a specific surface
The high purity silicon carbide powder is advantageously used as a material for producing an excellent silicon carbide single crystal having a decreased nuer of crystal defects. A process for producing high purity silicon carbide uses a high purity tetraethoxysilane or the like as the silicon source and a novolak-type phenol resin or the like as the carbon source.
Silicon carbide is produced commercially by reaction of a mixture of sand (silica) and coke (carbon) in an electric resistance furnace: (1) SiO2(1) + 3C (s) → SiC (s) + 2CO (g)
Silicon carbide crude is produced by mixing silica (SiO2) with carbon (C) in an electric resistance furnace at temperatures around 2,500 C. The chemical reaction in the SiC process may be represented by the formula: SiO2 + 3C SiC + 2CO.
Following the same method, we have developed another unique technology for producing high-purity silicon carbide (black and green powder) from metallurgical silicon. There is no analogue of this technology in the world, since all over the world it is produced with a purity ranging from 95% to 99%, and we – following our own technology – make up the silicon carbide purity to 99.9999%.
Silicon carbide, powder, max. particle size 75 micron, weight 500 g, purity 98.7%
Developing special, tailor-made silicon carbide powders together with our customers, makes up a significant portion of the ongoing effort in the global silicon carbide innovation teams. At the end of such a development process, we end up with a silicon carbide powder having unique properties that will improve the customer''s manufacturing process or their end products.
Silicon carbide tubes are produced through extrusion. The properties in the extrusion direction differ from the properties in other directions. Cold isostatic pressing is the powder compaction method conducted at room temperature, and it involves applying pressure from multiple directions through a liquid medium surrounding the compacted part.

Silicon Carbide (SiC) The annual production of silicon carbide (SiC) exceeds 800,000 t, making it by far the most used non-oxide ceramic. In the past it has been used almost exclusively as an abrasive material, which still accounts for a major part of its usage.
Green SiC Micro Powder always produced by jet milling process, ball milling process, and water pickled process. Although they have all gone through the acid-washed process, the Green SiC Micro Powder made by water sieving process is better. Appliion： The main purpose of silicon carbide micro powder is precision grinding and polishing.
