About Us:

Foshan Rising Technology Co., Ltd. is one of leader of China producer and supplier for silicon carbide refractory material, abrasives, blasting and surface preparation industries located in Nanhai Distrit, Foshan City, Guangdong Province.

Our products are with the highest quality for refractory bricks, un-shapped refractory purposes, crucibles, casting and painting, precision cutting, grinding ,lapping, polishing, sandblasting, shotblasting, anti-slipping purposes and other applications and industries. 

black silicon carbide containing SiC by about 98.5%, the toughness higher than that of green silicon carbide, mostly used for processing low tensile strength of material, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc.

Electrical conductivity Silicon carbide is a semiconductor, which can be doped n-type by nitrogen or phosphorus and p-type by aluminium, boron, gallium or beryllium. Metallic conductivity has been achieved by heavy doping with boron, aluminium or nitrogen. Superconductivity has been detected in 3C-SiC: Al, 3C-SiC: B and 6H-SiC: B at the same temperature of 1.5 K. Or aluminum. A crucial difference is however observed for the magnetic field behavior between aluminum and boron doping: SiC: Al is type-II, same as Si: B. On the contrary, SiC: B is type-I. In attempt to explain this difference, it was noted that Si sites are more important than carbon sites for superconductivity in SiC. Whereas boron substitutes carbon in SiC, Al substitutes Si sites.

It is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing. It is classified into black silicon carbide and black silicon carbide. Mechanical intensity of it is higher than fused alumina. Small coefficient of expansion, brittle property and good thermal conductivity.


This series of products are ideal kiln furniture in industrial kilns, and widely used in chemical industry, petroleum, environmental protection and so on.

Product Discription:
Black Silicon Carbide is produced in an electric resistance furnace from quartz sand and petroleum coke or anthracite at high temperature. The hardness and sharp particle shape of this material make it suitable for manufacturing of grinding wheels, coated products, wire saws, superior refractory materials and deoxideiser as well as for lapping, polishing and blasting.

Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite.

Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.

Electronic applications of silicon carbide as light emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907, and today SiC is widely used in high-temperature/high-voltage semiconductor electronics. Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as synthetic moissanite.
Silicon carbide with high surface area can be produced from SiO2 contained in plant material.
Because of the rarity of natural moissanite, most silicon carbide is synthetic.

It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600 and 2500 °C. Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material.The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1500 °C.

Synthetic SiC Lely crystalsThe material formed in the Acheson furnace varies in purity, according to its distance from the graphite resistor heat source. Colorless, pale yellow and green crystals have the highest purity and are found closest to the resistor. The color changes to blue and black at greater distance from the resistor, and these darker crystals are less pure. Nitrogen and aluminium are common impurities, and they affect the electrical conductivity of SiC.

Abrasives & Cutting Tools: In the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material. In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.

In 1982 an exceptionally strong composite of aluminium oxide and silicon carbide whiskers was discovered. Development of this laboratory-produced composite to a commercial product took only three years. In 1985, the first commercial cutting tools made from this alumina and silicon carbide whisker-reinforced composite were introduced by the Advanced Composite Materials Corporation (ACMC) and Greenleaf Corporation.
