Silicon Carbide (SiC) Properties and Appliions
Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.
Sintered ceramic - Silicon carbide
Our standard SiC sintered ceramic is sense silicon carbide SSiC : Sintered silicon carbide Pressureless sintered silicon carbide (SSIC) is produced using very fine SiC powder containing sintering additives. It is processed using forming methods typical for other ceramics and sintered at 2,000 to 2,200° C in an inert gas atmosphere.
TOKAI KONETSU KOGYO CO.,LTD-Super Refractories-
Silicon carbide refractories bonded with silicon nitride DC-N: This type of refractory (DC-N) has the advantageous features of both silicon carbide and silicon nitride. Since DC-N has excellent strength at a high temperature, it is possible to use refractory products which are smaller in thickness.
Carbide | chemical compound | Britannica
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

Chemical bonding of silicon carbide - ScienceDirect
Dec 01, 1999· Cassidy has mentioned the appliion of phosphate bonded silicon carbide refractories in steam generating boilers, and quoted the aluminium-phosphate containing products as possessing the best properties. According to this author, the phosphate bonded high alumina and SiC products exhibited radically different thermo-mechanical behaviour
US Patent for Monolithic graphitic castable refractory
Small amounts, typically from 1 to 3% by weight, of carbon fines and/or fine size graphite sources are commonly added to monolithic refractory castables, i.e., compositions of refractory aggregate mixed with a bonding agent which will develop structural strength and set, based on alumina and/or silicon carbide as a fine discontinuous phase filler.

Appliions Of Refractory Materials Engineering Essay
Some appliions require special refractory materials. Zirconia is used when the material must withstand extremely high temperatures. Silicon carbide and carbon (graphite) are two other refractory materials used in some very severe temperature conditions, but they cannot be used in contact with oxygen, as they will oxidize and burn.
A Comparison between Andalusite and Bauxite as Refractory
Refractory suppliers for their viability have to turn to alternative raw materials that can serve the same purpose. One such example is the use of andalusite refractories in appliions where bauxite is currently being used. South Africa is the biggest producer - supplier of high quality refractory grade andalusite and has no export restrictions.

Growth of Low-Defect SiC and AlN Crystals in Refractory
Refractory metal carbide technology, particularly, tantalum carbide (TaC), was originally developed for appliion in highly corrosive and reactive environments. The SiC group of Prof Yuri A Vodakov (for example, ) at Karmon Ltd in St Petersburg, Russia was the first to study and utilize the properties of refractory metal carbides, first
Silicon carbide is used to produce epitaxial graphene by graphitization at high temperatures. It is also acts asthe metallurgical deoxidizer material. Four main appliion areas of SiC: functional ceramics, advanced refractory, abrasives and metallurgical materials.
General Silicon Carbide Information Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C
