    • 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.
    • 描述了用于制造体的新型陶瓷白色陶瓷体,釉料和用于体的能量效率过程的组合物。 白炭黑体含有作为填充材料分散有石英颗粒的低熔点碱金属磷酸盐玻璃料的基质。 通常,将包含约50重量%至约80重量%的颗粒状石英填料和约20重量%至约50重量%的碱金属磷酸盐玻璃料的组合物加热至约约软化温度 碱性磷酸盐玻璃料的温度至约600℃。此后,通过将组合物在指定的温度范围内烧结约0.1小时至约10小时的时间,或通过在所指示的温度范围内热锻所述组合物, 温度范围。 本发明的新型釉料包括碱式磷酸盐玻璃料和任选的改性材料如遮光剂,颜料等。 本文所述的玻璃陶瓷白色陶瓷体可用于低温应用。
