  • Moulding compound, use thereof and a method for producing an oxide-ceramic sintered body
    Publication number: 20040012127
    Abstract: The invention proposes to produce a mixture that is shrink-resistant, or has a freely selectable degree of shrinkage, and can be used as a molding compound, and a method for producing a corresponding oxide-ceramic sintered body. The molding compound comprises an intermetallic compound and a wax. In the method for producing an oxide-ceramic sintered body, a green body is molded from a molding compound of this type, dewaxed and sintered in an oxidizing atmosphere to form a ceramic sintered body. The molding compound is suited for producing dentures and dental fillings.
