2014-10-7 · Silicon carbide has a high melting point of 2,700 °C and is therefore an important raw material for refractory and ceramic products. Another characteristic of SiC is its resistance against chlorine and strong acids, also at high temperatures. Thanks to a hardness of 9.6 Mohs, it is also
2019-4-23 · Silicon is a chemical element with syol Si and atomic nuer 14. It is a hard and brittle crystalline solid with a blue-grey metallic lustre; and it is a tetravalent metalloid and semiconductor. It is a meer of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive

Silicon Nitride is a high-melting-point ceramic material that is extremely hard and relatively chemically inert. The material is prepared by heating powdered silicon between 1300 °C and 1400 °C in an atmosphere of nitrogen. Then the powder of silicon nitride can be sintered to designed shape. As it is one of the most thermodynamically stable technical ceramic material with high hardness as
Carbide, any of a class of chemical compounds in which carbon is coined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack even at very high temperatures.
2019-4-19 · Silicon Carbide Fibers are extremely strong, oxidation-resistant fibers for high-temperature appliions available in both alpha- and beta-SiC compositions. American Elements can produce materials to custom specifiions by request, in addition to custom compositions for commercial and research appliions and new proprietary technologies.
they are difficult to seperate therefore it has high melting point. In case of SiF 4 no dimer is formed te boiling point is diferent for different chemicals and silicon carbide ceramics
2019-4-24 · Silicon carbide is an important material in TRISO-coated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors such as the Pebble Bed Reactor. A layer of silicon carbide gives coated fuel particles structural support and …
2016-7-29 · Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years.
silicon Carbide is our main products, we can produce both black one and green one, it can be used in many areas, silicon carbide / Sic micron whisker (Sic-w) has the good chemistry stability, low heated expansion, high efficiency of heat conductivity, electrical resistance comparing with metal being in the opposite direction, very hard and the level over 9.5 of Moss''s.
