The invention relates to a composite ceramic material which comprises: The invention also relates to a ceramic powder composition, processes for the preparation of the composite ceramic material and the ceramic powder composition as well as uses thereof.

Composite ceramic material comprising zirconia

The invention relates to compositions based on Ce-stabilized ZrO, and single- and multi-colored blanks made from oxide ceramics, and a process for their preparation, in which oxide ceramic powder is coated with a coloring substance, the coated powders are preferably graded and at least one colored powder is filled into a compression mould, the colored powder or powders are compressed to produce a shaped body, and the compressed shaped body is sintered to produce a blank, and to the use of these blanks for the preparation of dental restorations. The compositions exhibit high fracture toughness and high flexural strength.

Shaded zirconia ceramics

Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools and which subsequently can be converted into lithium silicate products showing high strength.
