Refractory Brick-Nitrid bonded Silicon Carbide Brick

High strenght,high thermal conductivity Good thermal shock resistance &corrosion resistance w/ ISO9002 Certification

Refractory Brick-NBSC Nitride bonded Silicon Carbide Brick

For Non-ferrous Metallurgy and Ceramic Industries

High Quality silicon carbide refractory products have been developed by Luoyang Refractory Mineral Co., Ltd featuring high strength, high thermal conductivity, good thermal shock resistance and corrosion resistance etc. The main properties have been tested and evaluated by independent testing outside China, and the results are good. So far the products have been approved by adecade of large ccompanies abroad, over 80% of its output have been supplied to more than 10 countries and regions, especially in Europe and America. Meanwhile the products have been supplied to many major enterprise in China such as nonferrous metallurgy industry and so on.
