Characteristics:high hardness and strong cutting ability, stable chemical

Green silicon carbide

Green, crystal structure, high hardness and strong cutting ability, stable chemical characteristics, good thermal conductivity. Microcosmic shape is a hexagonal crystal, Mohs hardness is 9.3, Vickers hardness is 2670−2815 kg/mm2, micro−hardness is 2940−3300kg/mm2. Among abrasives, silicon carbide’s hardness is higher than corundum, and ranked below diamond, CBN and boron carbide. Density generally viewed is 3.20−3.25g/ mm3 , natural bulk density is 1.2−1.6g/ mm3 , specific gravity is 3.20˜3.25g/ mm3. Raw material are petroleum coke and quality silicon sand, appended with salt, then smelted in electric arc furnace. Mechanical strength is higher than corundum.

Main applications: solar and semiconductor wafer wire sawing; crystal and ferrite polishing; ceramic and special steel precision polishing; bonded and coated abrasive tools; cutting and polishing; non−ferrous metal lapping such as glass, stone, agate and high−grade jewelry; high−grade refractory materials , engineering ceramic, heating elements and thermal elements.

For wire-sawing of solar and semi-conductor

Usage:

Green silicon carbide is used for wire−sawing of monocrystal silicon, polocrystalline silicon, potassium arsenide, quartz crystal etc, it is the engineering processing material in solar photovoltaic industry, semi−conductor industry and piezoelectric crystal industry.

Feature:

1.high purity and large crystal silicon carbide ingots ensure the excellent cutting capability and stable physical condition.

2.Grains are isometric with sharp edge, which ensure the even self-sharpening capability as cutting material and minimum TTV of the products been cutted.

3.Particle size distribution is narrow and even.

4.High heat−resisting and refractoriness under load guarantee the small wire expansion in processing, suitable to all kinds of wire saw machine.

5.Grain surface possessed specially, micro−powder with clean surface and easily fit cutting fluid, such as polyethyleneglycol and so on.

Company Information

Henan Ruishi Investment Group Co., Ltd., formerly known as Yichuan Ruishi Abrasives Co., Ltd., was founded in 1992. The company mainly produces all kinds of abrasives, special refractories and metallurgical materials. After nearly 20 years of rapid development, the company has developed into a stock−holding company with seven wholly−owned subsidiaries, including a bauxite calcination plant, a smelter plant, a sand−making plant, a new energy solar−powered wire cutting plant, a renewable resource company, and an international trading company. The company has the rights for import and export; it is also one of the top−100 export bases in Henan Province. The production base of the group covers an area of 440 mu. It has 350 employees, and a registered capital of 72 million yuan; it is equipped with six domestic first−class large−scale 3600KVA/360KVA high−temperature furnaces, and six automatic Barmac production lines; in order to ensure the stability of raw materials, the company built 4 shaft kilns, to be dedicated to firing first−grade alumina blocks used for smelting, which has an annual production capacity of up to 150,000 tons. The new−type energy−saving composite corundum developed by the company has a production capacity that ranks first in the industry worldwide. The products took the lead in the industry in passing the ISO9001: 2000 Quality Management System certification, which are exported to more than 20 countries and regions, including the United States, Russia, Japan, and Korea. In 2010, the total assets of the Group reached 159.09 million yuan; the sales income was up to 256.33 million yuan, and the taxes amounted to 24.93 million yuan, having created good social and economic benefits and made outstanding contributions to the society.
