HIGH THERMAL EXPANSION COEFFICIENT CERAMIC SINTER AND A COMPOSITE BODY OF THE SAME AND METAL

HIGH THERMAL EXPANSION COEFFICIENT CERAMIC SINTER AND A COMPOSITE BODY OF THE SAME AND METAL

The ceramic sinter is composed of a metal oxide selected form Al₂O₃, MgO, ZrO₂, BaTiO₃, GeO₂, Fe₂O₃, WO₃, CaTiO₃ and MgFe₂O₄, and 10-90 vol. % of metal fluoride which has an electronegativity difference of not less than 2.5 between fluorine and the metal element.The ceramic sinter has a thermal expa...

Beschreibung
Zusammenfassung:The ceramic sinter is composed of a metal oxide selected form Al₂O₃, MgO, ZrO₂, BaTiO₃, GeO₂, Fe₂O₃, WO₃, CaTiO₃ and MgFe₂O₄, and 10-90 vol. % of metal fluoride which has an electronegativity difference of not less than 2.5 between fluorine and the metal element.The ceramic sinter has a thermal expansion coefficient which can be chosen between 10-20x10⁻⁶/°C and is suitable for bonding with general use metals such as stainless steel to form a composite body of the ceramic sinter and the metal, without causing a substantial thermal stress at the junction thereof.
