Carbon Based Refractories – IspatGuru
Carbon based refractories behave differently than the typical ceramic refractories, primarily because carbon based refractories are conductive rather than insulating. All carbon based refractory lining systems perform as a ‘conductive cooling system’ as opposed to a classic definition of a refractory lining that is typically an ‘insulating system’.
For example, the maximum operating temperature of Silicon Impregnated SiC (SISC/RBSIC) Bonded Silicon Carbide is 1375 C, the melting point of silicon. Production Silcarb manufactures its NBSIC in a very controlled electric furnace where temperatures are very accurately maintained and pressures are regulated through the cycle.

The present study was undertaken to establish a methodology for character rising silicon carbide-based refractories, as detailed information is unavailable in the literature on this point.
Glass Tank Furnace Refractories - Rongsheng Kiln …
When choosing refractories used in glass tank furnace, these factors such as furnace types, appliion parts, damage mechanisms, glass egories, colors and so on should be considered. Glass melting furnace refractory materials should have excellent molten glass and gases corrosion resistance.
Corundum silicon carbide plastic refractory is an advanced refractory material with excellent wear resistance, superior adhesion and high service temperature (1200 ). Meanwhile, it is simple in construction process. It is known for its short construction period and
How Is the New Technology Applied in Refractories?
For example, SiC whiskers grown by in-situ synthesis technology can significantly enhance the strength and toughness of the Al2O3-C refractory. Self-propagating High-temperature Synthesis (SHS) With the development of self-propagating synthetic, it has been applied in the field of refractories.

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 hardness, strength, and resistance to chemical attack even at very high temperatures.

Refractory - Wikipedia
All refractories require anchorage systems such as wire formed anchors, formed metal (for example, hexmetal) or ceramic tiles to support the refractory linings. The anchorage used for refractories on roofs and vertical walls are more critical as they must remain able to support the weight of refractories even at the elevated temperatures and operating conditions.
