The thermal conductivity of black silicon carbide reflects the speed of heat transfer, which is needed in many cases, so it is a parameter that companies value in the purchase process, but it is not static, it will change with the surrounding environment during use Change and change.
With the development of electricity now, our life has been inseparable from the use of electricity, the development of the power electronics industry is becoming more and more rapid, but its development is also inseparable from the promotion of black silicon carbide powder, it as an important material for the production and manufacturing of the power electronics industry, its technological innovation and use is inevitable.
Brown corundumAbrasives can be divided into three grades and five echelons according to the level of alumina content. Among them, primary brown corundum and secondary brown corundum are the most commonly used abrasive products in industry.
In daily life, many people will confuse some abrasives or some rough stones, thinking that they are all the same, and their uses are also the same. For example, some people will call emery, silicon carbide, and brown corundum silicon carbide. Is this name really reasonable? Many people don’t know their specific uses when they can’t tell the difference, so today I will take you to see the difference between emery, silicon carbide and brown corundum.
Nature and usefulness. Corundum is a pure crystalline alumina (AI2O3), due to often containing a certain mixture and a variety of divergent colors, such as chromium containing red, chin containing blue, iron containing brown, manganese containing rose, corundum hardness in the natural mineral second only to diamond, primary as a high-grade grinding material, can be made into corundum grinding wheel, grinding disc, grinding paper and grinding powder, etc., mainly used for the polishing and processing of metal finished products, can also be used as the instrument fast rotation department bearing, Corundum powder can also polish the optical glass of tight instruments, while transparent and brightly colored corundum can be used as a gemstone.
Green silicon carbide It is a non-metallic mineral product produced by quartz sand (SIO2), petroleum coke (C) and sodium chloride (NAC1) as basic raw materials at high temperatures above 2000 degrees Celsius. Green silicon carbide is suitable for grinding cemented carbide and hard brittle metal and non-metallic materials, such as copper, brass, aluminum and magnesium and other non-ferrous metals and gemstones, optical glass, ceramics and other non-metallic materials.
When it comes to brown fused alumina, everyone first thinks of its hardness and wear resistance, etc., but there is another characteristic of brown fused alumina that is ignored by everyone, and that is its toughness. Today, the editor will take you to briefly understand the toughness of brown fused alumina.
Green silicon carbide is an abrasive, in the form of green powder, its appearance, has played an important role in the processing of cemented carbide, glass, ceramics and non-metallic materials. The silicon content in green silicon carbide can reflect the quality of the product, and I will specifically talk about how to identify its silicon content.
Green silicon carbide materials can be used to produce green silicon carbide grinding wheels, its color is green, can be widely used to process hard and brittle materials of workpieces, but generally not suitable for processing materials with greater toughness. What are the performance characteristics in the process of use?
Black corundum and Brown corundumIn general, the raw materials are the same, but there are still great differences in actual use, and the difference between black corundum and brown corundum can be manifested in the following aspects:
