Brown Corundum used in industry

H&X Brown Corundum silicon powder as an engineering ceramic material, which is widely used in industry. Mainly used for ultra-high-temperature gas turbines, aircraft engines, turbine blades, heat exchangers, furnaces, etc. Heat-resistant coating can also be used for rockets and nuclear reactors. For insulation materials, machinery wear-resistant materials, heat engine materials, cutting tools, advanced refractories and anti-corrosion, H&X silicon carbide manufacturers sealing components. Calcium silicon ceramic gas turbine combustor to do, mechanical seal rings, transmission of electromagnetic pump liquid aluminum pipes and valves, permanent mold, steel separation ring.

Brown Corundum basic introduction

After white fused alumina powder as an industrial raw material, in the arc melting temperature above H&X buy brown fused alumina degrees cooling is made by crushing plastic, magnetic separation to iron, screening into a variety of particle size, its dense texture, high hardness, sharp grain formation shaped, white fused alumina for the manufacture of ceramics, resin bonded abrasives and grinding, polishing, sandblasting, precision casting (casting special corundum), etc., can also be used to manufacture advanced refractories, codenamed "WA" on internationally accepted standards, national consistent standards, most for export, there is a certain amount of supply H&X Alumina Grinding Media users. Product size in accordance with international standards and national standards of production, processing granularity according to user requirements. Universal size No. F4 ~ F220, its chemical composition varies depending on grain size. Prominent feature is the small crystal size, impact resistance, since the mill processed if broken, the particles are mostly spherical particles, the surface of the dry-cleaning, easy binding agent.

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.

The main raw material of silicon carbide abrasive

H&X Aluminium hydroxide powder is black quartz sand, petroleum coke as the main raw materials, smelting electric arc furnace. Its hardness between corundum and diamond, corundum higher mechanical strength, brittle and sharp. It has a certain electrical conductivity and thermal conductivity. Black silicon carbide Usage: abrasives, metallurgical deoxidizer, high temperature materials, semiconductors, carbon fiber (1) as an abrasive, can be used for abrasives, such as grinding wheel, Whetstone, grinding, sand tile and so on. (2) as a metallurgical deoxidizer and high temperature materials. Silicon carbide has four major application areas, namely: functional ceramics, advanced H&X Sic Refractory, abrasives and metallurgical materials. (3) high-purity single crystal can be used for the manufacture of semiconductor manufacturing silicon carbide fibers. (4) silicon carbide is very hard and has excellent thermal conductivity properties, is a semiconductor, resistant to oxidation at high temperatures.

Fused quartz manufacturer details

Fused silica sand Which H&X pink fused alumina from the price and quality
Each company trading fused silica sand, will have a common point, that is the price of fused silica sand, fused silica sand price is the prime consideration customer choice, and our factory is located in the resource-rich quartz sand birthplace of Jiangsu Lianyungang, which is why I plant a big advantage in doing quality assurance while melting quartz sand prices in the peer also has a large advantage. The production of quartz sand, fused silica sand, silica powder, is signed by the National Building Materials Bureau for H&X silicon carbide micropowder products. With advanced processing equipment and production technology of quartz, relying on domestic resources, abundant high-quality quartz, following today's ever-changing market, according to market demand, developed a variety of high quality products.
