Title: Ceramic composition for enamel-coating of titanium material
Inventor: KAMIYA TADAO
IPC: C04B33/14
Filed: 1992-12-25
Abstract: PURPOSE:To provide a ceramic composition for the enamel-coating of a titanium material, having excellent physical and chemical properties and bio-compatibility and useful for the restoration of dental crown. CONSTITUTION:This ceramic composition contains 71-78% SiO2, 12-17% Al2O3, 5-8% K2O, 5-8% Na2O and 2-5% B2O3 as essential components and further contains 1.5-5% BaF2 and/or 1.0-3.0% CaF2. The thermal expansion coefficient of the ceramic composition is somewhat lower than that of titanium material to enable the prevention of crack generation in the ceramic material in the case of enameling on a titanium material. Since the ceramic material can be welded at a temperature lower than the temperature (900 deg.C) to cause considerable oxidation of the titanium material, it gives strong enameling strength and is resistant to peeling after application of the enameled titanium material to the oral cavity, excellent in acid resistance and stable in the oral cavity.
