Title: PRODUCTION OF THORIA WARE

Abstract

The production of thoria ware of very low porosity by the slip casting of pure thoria is described. It comprises dry milling calcined thoria to obtain particles ranging up to 11 microns in size and having 60% of particles less than 2 microns, forming an aqueous slip of the milled thoric casting the slip and firing the dry cast at a sintering temperature of from 1600 to 1825 d C. The preferred composition of the slip is 1600 grams of thoria in each liter of slip. The preferred pH of the slip is 1. When thoria of 99.9% purity is used the slip is suitable for casting for as long as six weeks after preparation.
