More Information
Summary: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.
