Abstract
By utilizing a correctly constituted suspending medium and binder, stable slip-casting powder mixtures of tungsten carbide and cobalt were prepared. The stability of the suspension was governed by the pH of the medium; casting rate was dependent on the formulation of the slip, and particularly on the solid concentration. Close control of these variables permitted the use of plaster of Paris moulds for casting sound, dense bodies of the powder mixtures, which were sintered for final densification without the appearance of any defects.
