Electro-fused mullite bricks & blocks;
Fused mullite refractories are widely used in metallurgy furnaces. Also in the construction materials industry, crucibles, ceramic industry, glass furnaces, petrochemical industry.
Main advantages are low thermal conductivity, low thermal capacity, high heat resistance, directly contact the flame, strong resistance to thermal shock.
