Refractories are high temperature resistant materials that constitute the linings for high-temperature industrial furnaces and reactors and other processing units. In addition to being resistant to thermal stress and other physical phenomena induced by heat, refractories must also withstand physical wear and corrosion by chemical agents. Refractories are more heat resistant than metals and are […]
Technical
SUBSTANCE: present invention relates to a fusion-cast brick having high content of zirconium dioxide, which can be used as a refractory lining of a glass-melting furnace in contact with molten glass mass. The refractory brick contains (wt %): zirconium dioxide (ZrO2+Hf2O) more than 85, silicon oxide 1-10, aluminium oxide 0.1-2.5 and dopants, wherein standard deviation […]
