These products have high refractoriness, thermal conductivity and good abrasion, mechanical and thermal shock resistance. These products offer low wet ability to non-ferrous molten metals and superior corrosion resistance thus minimizing contamination of the alloy products and operation cost.

They are widely served in the hearth, tuyere, tap hole of blast furnace, aluminum electrolyte reduction furnace, high temperature kiln furniture, thermal treatment furnaces, pouring spouts, ladles and troughs to non-ferrous metals, they can be used in contact with melted metals and slag or acid atmospheres.
