Abstract
A method of making a shaped article comprises mixing a refractory powder with an aqueous acidic phosphate solution, subjecting the mixture thus formed to high shear to form a plastic mass, shaping the mass, and hardening the shaped mass at a temperature below the sintering temperature of the refractory powder. By this method articles of useful hot-strength can be obtained without having to employ the high temperatures required for sintering.
