Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Silicon carbide bricks are a kind of refractory brick used high purity silicon carbide(SIC) and industrial silicon powder as the primary materials. Silicon carbide bricks have the advantages of wear resistance, good erosion resistance, high strength, excellent thermal conductivity and thermal shock resistance, good oxidation resistance, low porosity and better adhesion resistance,etc.
Silicon carbide is a new generation deoxidizer, which can be used instead of expensive conventional deoxidizer such as pdofsifer and alloyed powder. Silicon carbide can be used as deoxidizer for common steel, alloyed steel and special steel. Silicon carbide is characterized by faster deoxidation, earlier scorifiion, reducing atmosphere, and rich foam.

12/3/2020· Generally, refractories are classified as basic, high alumina/silica, fireclay and insulating. There are also classes of “special refractories” which include Silicon Carbide, Silicon Nitride, Graphite, Zircon, Zirconia, fused cast and several others. Most refractory materials
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.

Silicon carbide powder is micron graded silicon powder which use JZFZ equipment to conduct ultra-fine grinding. Currently, silicon carbide powders are mainly 1200 #, 1500 #. The silicon carbide powder is mainly used in the abrasives industry, so the classifiions of the micronized have special requirements.
Silicon carbide with nitride or oxide bonds, together with a range of cements. Furnace lining bricks, burners, tap-hole blocks, launder systems, pouring spouts and bespoke shapes produced to customer specific requirements.
If you want to buy cheap black silicon carbide, please click our products: Black Silicon Carbide for more information! As a result of the above measures, the life of the furnace lining has been doubled and the consumption of refractories has been reduced by half( black corundum ).
This test method covers the evaluation of the oxidation resistance of silicon carbide refractories at elevated temperatures in an atmosphere of steam. The steam is used to accelerate the test. Oxidation resistance is the ability of the silicon carbide (SiC) in the refractory to resist conversion to silicon dioxide (SiO 2 ) and its attendant crystalline growth.
