Shandong Qingzhou Micro powder Co., Ltd., founded in 1995, is an export-oriented enterprise with registered capital of RMB5.2million & taking area of 40000 square meters specializing in silicon carbide micro powder. At present, the company has been one of the largest professional manufacturers for silicon carbide micro powder with self-support import & export rights & annual output of over 3000 to tons for silicon carbide micro powder. The company is the appointed high-tech enterprise of Department of Science & Technology of Shandong Province (Approval 2002 No. 184) with serial number of 44-07153A and has now passed ISO9001: 2000 Quality Management System Certification.

The abrasive material, one of mainly application areas of our product, can be used in processing for low-tension paper material, brittle material, ultra hard material, silicon semiconductor material etc, such as cast iron, brass, aluminum material, stone material, glass, ceramic, hard alloy, monocrystal line silicon, piezocrystal and so on.

The engineering ceramics, one of the main application areasof our product, can be made into high grade refractory. It mainly contains reactive sintering silicon carbide (SiSiC) products & recrystal silicon carbide (RSiC) products, such as decking, square girder, muzzle and other kiln tools under high-temperature conditions. The materials made by reactive sintering (SiSiC), pressureless sintering (SSi)and silicon nitride bonded silicon carbide (NSiC) can be used for making heatproof, wearproof & corrosion resistant mechanical sealing components and vehicle brake linings, each kinds of sliding bearing & rolling bearing, each kinds of valve components, each kinds of nozzle for high-temperature, high-pressure & corrosive liquor & gas etc. As the gas scavenging & filtering material, DPF that made of SiC micro-powder is the necessary component of new-type auto-exhaust purification treatment with wide applicable prospect. The conducting paint, another application area of our product, mainly applies to the inside & outside paint of various multicolor kinescope, each kinds of marine paint etc.

After several years development, the company has made many technological achievements. Our High Purity Fine Ceramic Silicon Carbide Micro-powder has got State Main New Product Certificate of five ministry of the country with the project number of 98GD41D7400042. Our self-developed jet mill has got the national patent and filled the gap of this area in our country. The new factory possesses a building area of over 8000 square meters and has been equipped with internal advanced online supervision, online control micro-powder production line and high-purity fine ceramic micro-powder production line etc. The former production equipments have also been renovated

Continually and the whole production flow has reached comparative advanced level. With advanced & complete supervision methods, our high-standard quality inspection center can make systematic & complete analysis & supervision for SiC Micro-powder.

Developing the international market actively, the company has obtained superior economic benefits & social benefits and fulfilled the quick development. With excellent & stable performance, the products, 80% of which have been marketed across Japan, South Korea & USA and other countries and regions, and we have been highly appraised at home and abroad.
