  • Method of Making Ceramic Articles with Multiple Distinct Regions of Distinct Density
    Publication number: 20120313279
    Abstract: A method for producing ceramic articles with multiple distinct regions of density by blending pore formers of different types or amounts with ceramic particles to create multiple pore former/ceramic particle mixtures. The mixtures are placed in a divided die cavity, divider removed and subjected to compaction under pressure to produce a compacted billet. The compacted billet is thermally processed to volatilize organics from the billet and sinter the billet, creating a cohesive billet of ceramic having two or more regions of density.

  • Novel whiteware bodies and energy efficient process for their production
    Patent number: 4212924
    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.
