Abstract
Novel ceramic whiteware bodies, glazes and compositions for the bodies and energy efficient processs for the fabrication of the bodies are described. The whiteware bodies contain a matrix of a low melting alkali phosphate frit having quartz particles dispersed therein as a filler material. Typically, a composition comprising from about 50% by weight to about 80% by weight of particulate quartz filler and from about 20% by weight to about 50% by weight of an alkali phosphate frit is heated to within a temperature range from about the softening temperature of the alkali phosphate frit to about 600.degree. C. Thereafter, the body is fabricated either by sintering the composition within the indicated temperature range for a period of time from about 0.1 hours to about 10 hours or by hot forging the composition within the indicated temperature range. The novel glaze of the invention comprises an alkali phosphate frit and optionally modifying materials such as opacifiers, pigments and the like. The glazed ceramic whiteware bodies described herein may be used in low temperature applications.
