Sic Refractory is silica core

Sic Refractory as a core raw material silicon feedstock plays an irreplaceable role in the production and supply base silicon feedstock. It has the H&X white fused alumina physical and chemical properties, making it occupies a pivotal in aviation, aerospace, electronics, machinery, and the rapid development of today's IT industry position, especially its intrinsic molecular chain structure, crystal shape and lattice variation, it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion-resistant, the piezoelectric effect, resonance effect and its unique H&X silicon carbide grit properties, making it plays an increasingly important role in many high-tech products, such as, IT industry's core technology products - computer chips, fiber optics, electronics industry resonator, new electric light, highly insulating sealing materials, aerospace equipment, military technology products, special optical glass, chemical analysis equipment, etc., from do not open these basic materials.

Our country present situation and countermeasure of Sic Refractory

microcrystalline alumina abrasive
The SG abrasive H&X calcium granules rely on import in our country, due to a few countries such as America, France's technology and market monopoly, and limited imports, at the same time, some foreign do abrasive has begun large-scale preempted market in our country, after China's accession to the WTO, this kind of circumstance also exacerbate, in this way, not only lose a lot of foreign exchange. And make the national industry of our country is facing huge impact. In view of the above situation, the author thinks that the abrasives industry in our country in the aspect of the development of microcrystalline alumina abrasive should adopt the following countermeasures, in response to foreign abrasive abrasive H&X garnet manufacturers of our market.
(1) to the development and application of microcrystalline alumina abrasive, and to realize the industrialization as soon as possible, to change the abrasives industry in our country at present large scale and low content of science and technology
(2) the international tendency, keeping a close eye on abrasives industry holding information, fight for change in a short time "generic" for "development";
(3) the technical secret job, put an end to loss of our country in this respect technology at home and abroad.

Brown Corundum product size

Product size in accordance with international standards and national H&X fused silica manufacturers of production, processing granularity according to user requirements. Universal size No. F4 ~ F320, its chemical composition varies depending on grain size. Prominent feature is the small crystal size, impact resistance and self-processing mill with broken particles are mostly spherical particles, sharp Pai corundum with high purity, dense texture, bulk density, self-sharpening, good toughness, H&X Aluminium hydroxide powder material Features ultra-low levels, which is made using abrasive grinding sharp, low fever, grinding ratio, and the use of less buildup; made of sintered abrasive with dark blue color after firing, can not afford to mesh cracks, no rust, suitable for the manufacture of ceramic, resin and high abrasive grinding and polishing.
