Also known as silicon carbide emery or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal), wood (need to increase the production of green silicon carbide salt) and other raw materials in high temperature resistance furnace smelting. The main application of silicon carbide, as an abrasive, can be used for abrasive, such as wheel, Whetstone, grinding, sand tiles etc.; as metallurgical deoxidizer and high temperature materials; high-purity single crystal can be used to manufacture semiconductors, silicon carbide manufacturing fibers. Quality specifications, silicon carbide abrasive level technical conditions according to GB / T2480-96; abrasive particle size and composition according to GB / T2477-83, abrasive particle by particle size fraction 4, # 5, # 6, # 7, # 8, 10 #, 12 #, 14 #, 16 #, 20 #, 22 #, 24 #, 30 #, 36 #, 40 #, 46 #, 54 #, 60 #, 70 #, 80 #, 90 #, 100 # , 120 #, 150 #, 180 #, 220 #, 240 #. Ning Xia Xingkai Silicon Co., Ltd., specializing in the production of the above specifications silicon carbide size sand (grit), silicon carbide of sand / powder (7-70 #, 0-10mm, 80F-325F paragraphs), silicon carbide sand F (F12-F1200 each number), up to 99% purity of the product, the company's products are widely used in the field of grinding (grinding tools such as grinding wheels, abrasive cloth, all kinds of abrasive sandpaper, etc.), the field of photovoltaic (crystalline silicon cutting, etc. ), engineering / special ceramics (silicon carbide crucible, etc.), refractory field (batts, lining, etc.), metallurgy (deoxy reduction, etc.) and in addition more than 10 fields, creating lasting value for our customers across the industry, while wide acclaim. Relying Ningxia Ning Xia Xingkai low ash, low sulfur, low phosphorus and high calorie, high mechanical strength, high chemical activity, high specific resistance and other characteristics of the West too anthracite as raw material for the production of coal washing and processing carried out ultra ash, low sulfur coal products. High purity silica as raw materials were selected for silica wash process to produce uniform particle size, SiO2 content of more than 99℅ quartz sand. Reuse Ningxia sufficient power resources to clean coal and high-purity silicon carbide smelting quartz sand, to produce the highest international standards of silicon carbide products, silicon carbide abrasive products are widely used in manufacturing, refractories, steel deoxidizer, anti-slip material, petroleum, chemical, metallurgy, electrical, electronics, aerospace, automotive and other fields, as technology advances, silicon carbide in the field of optical materials, thin film materials, anti-radiation, a high-temperature pressure sensors and ultraviolet detectors, and other new material is more show a more broad application prospects. We persist in using corporate culture to enhance the core competitiveness of enterprises to establish a good image in the development community. "Honest and trustworthy, quality-oriented, mutual benefit, the pursuit of excellence" business philosophy, "customer first, good faith to the letter" for the purpose, respected "standard, fine, efficient and safe. Ning Xia Xingkai people are tirelessly efforts to revitalize the Chinese silicon carbide cause for triumph played in this, Ning Xia Xingkai staff warmly welcome you to visit and cooperation and exchanges for a better tomorrow.
