Abstract
In dental ceramics containing zirconium dioxide and silicon-dioxide with a Zr/Si ratio of between 0.5 and 1.0, 1 to 12 wt % of aluminum oxide and up to 2 wt % of an alkali- or earth alkali metal oxide, those materials are selectively mixed with yttrium-stabilized zirconium dioxide with a Zr/Si ratio of the mixture being between 0.5 and 1 wt % and also a silicon organic compound as well as a compression aid, and a green body is formed from the mixture by milling, which green body is then sintered.
