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.

Advantages of natural corundum

Natural diamond grinding H&X carbide silicon of slightly less than white corundum furnace, but its self-willed, and has a characteristic shell-like section of the mouth, the advantage of grinding parts finish, sand marks few and shallow. Fine grinding and uniform, to improve product quality, as Emery is unique. Natural diamond grinding time is short, high efficiency, low cost, short life can H&X fused silica manufacturers for the lack.
Natural corundum called garnet, which is the condition of the sky because it's produced, is a silicate mineral. Emery grinding raw materials through a simple process can be divided into several levels, classification and other methods of screening, great hardness, which is about Mohs 7-8 degrees. Usually a brown powder particles. Metals for industrial sandblasting, grinding and other purposes.

Alumina Refractory

Bauxite (aluminous soil; bauxite), also known as alumina or bauxite, main ingredients are aluminum oxide, hydrate alumina containing impurities, is an earthy mineral. White or grey, brown yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, H&X silicon carbide abrasive powder, opaque, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.
Main ingredients
The scientific name bauxite bauxite, bauxite. Its composition is extremely complex, a variety of geological sources vary the floorboard of the hydrous alumina ore. As water soft LvShi, hard LvShi monohydrate and sanshui LvShi (Al2O3 · 3 h2o); Have a plenty of diaspore and kaolinite (2 sio2, Al2O3, 2 h2o) company; Some is given H&X Alumina Oxide to with kaolinite, and with higher content of kaolinite, the form for general bauxite or kaolinite clay. Bauxite is generally formed by the chemical weathering or exogenous, there are few pure mineral, mineral always contains some impurities, more or less contain clay minerals, iron ore, titanium minerals and clastic heavy minerals and so on.
Bauxite definition names is not enough unity, this is related to resources from all countries and industrial demand. Name of various periods are inconsistent, but basically the same. In China it is generally believed: "bauxite refers to the aluminum content of ore is higher (40%), al-si ratio (A/S (2.5 or higher) is greater than 2.5, which is less than the numerical value is called clay or shale or aluminum bauxite rock". In China's proven reserves of bauxite, LvShiXing monohydrate bauxite accounts for about 98% of the country's total reserves.
