ABSTRACT:
Compacted refractory shapes having sufficient densities for lining metal melting furnaces and use at service temperatures of 3,400.degree. to 3,900.degree. F to retain molten metal are formed in place by bonding refractory particles of alumina, for instance, with aluminum hydroxide generated by the reaction of aluminum with water in the presence of a corrosion accelerator, and either with or without a reaction control agent satisfactory for eliminating or significantly suppressing the evolution of hydrogen, nitrogen dioxide, hydrogen chloride, or the like from the reacting mass or for reducing the rate of reaction corrosion.
