Products shaped brick

silicon carbide is artificially synthesized high-quality inorganic nonmetal material,integrated by covalent bond. Its rigidity is only inferior to diamond; melting point 2600℃; real density 3.21g/cm3; thermal conductivity reaches 8.37W/mk; silicon nitride's melting point is 1900℃mohs hardmess 9real density 3.19 g/cm3thermal conductivity 1thermal conductivity 15W/mk. Silicon nitride combined with silicon carbide is a new-type high-performance fireproof products combined with properties of both sides, with stable chemical properties. Its folding strength at normal temperature is 4~8 times than that of ordinary fireproof material 2~3 times than traditional silicon carbide products（clay combined with silicon carbide）its heat-transfheat-transfer coefficient is 7~8 times than that of ordinary fireproof materialits thermal expansion coefficient is only half of ordinary fireproof material.Practice has proved: silicon nitride combined with silicon carbide products（150×150×15）does not present crack through 30 times of water-cooling directly from 1100℃ possesses preferable thermal shock stability. It also possesses the fine properties of temperature creepresistance、 antacid、alkali resistance、antioxidation. It is against molten metal corrade such asAl、Pb、Sn、Zn、Cu、etc, fine insulativityhigh resistance at normal temperature. Using silicon nitride combinedcombined with silicon carbide is the ideal fireproof material for enterpries to improve the quality of products and enhance economic efficiency.

Physical chemical properties targets of silicon nitride combined with silicon carbide produced by Fudang Company.
