  • Non-dense sintered ceramic molded body having at least two layers
    Patent number: 11034051
    Abstract: A non-dense sintered ceramic molded body having at least two layers, wherein a first powdery ceramic material forming a layer is contacted with at least a second powdery material forming at least a second layer. The body has a color gradient and maintains dimensional stability during sintering and forming. An admixing component and a common sintering temperature are used to control the volume decrease of the layers during sintering.

  • PROCESS FOR PRODUCING A NON-DENSE SINTERED CERAMIC MOLDED BODY HAVING AT LEAST TWO LAYERS
    Publication number: 20190337185
    Abstract: A process for producing a non-dense sintered ceramic molded body having at least two layers, wherein a first powdery ceramic material forming a layer is contacted with at least a second powdery material forming at least a second layer; said first powdery material has a presintering temperature T1 that is higher than the presintering temperature TS of said at least second powdery ceramic material; the course of a curve of shrinkage S1 of said at least first powdery ceramic material differs from the course of a curve of shrinkage S2 of said at least second powdery material, wherein curve of shrinkage S1 is shifted towards higher temperatures as compared to curve of shrinkage S2; and the layers are subjected to a common temperature treatment at a presintering temperature TS that is lower than the presintering temperature T1 and at least equal to T3 to cause sintering that remains in a stage of sintering that has not proceeded to the theoretical density; wherein the curve of shrinkage S1 is modified by admixing

  • LITHIUM SILICATE GLASSES OR GLASS CERAMICS, METHOD FOR PRODUCTION THEREOF AND USE THEREOF
    Publication number: 20130295523
    Abstract: The invention relates to glass ceramics based on the lithium metasilicate system (Li2O SiO2 (Li2SiO3)), which are mechanically processible in a simple manner in an intermediate stage of the crystallization and, after complete crystallization, represent a high- strength, highly translucent and chemically stable glass ceramic.
