More Information
Summary:The invention relates to a chromium-zirconium refractory material, a preparation method thereof and a chromium-zirconium electrode brick. The chromium-zirconium refractory material comprises the following raw materials in percentage by mass: 10-30% of chromium oxide powder, 0-30% of chromium oxide synthetic powder, 46-80% of zirconite powder and 1-2% of titanium dioxide. The chromium oxide synthetic powder comprises the following raw materials in percentage by mass: 92.4%-97.5% of chromium oxide powder, 2%-4.5% of titanium dioxide, 0.5%-1.8% of silicon oxide powder, 0-1.5% of zirconium oxide powder, 0-3% of zirconite powder, 0-1.5% of alumina powder and 0-3% of fused zirconia corundum brick powder. In the chromium-zirconium refractory material, the mass fraction of the chromium oxide powder is 10%-30% but not 30%. The chromium-zirconium refractory material shows relatively high resistivity and excellent molten glass erosion resistance under the high-temperature condition of greater than or equal to 1400 DEG C
