Gallium alloy for dental restorations

Abstract

Abstract A gallium alloy for dental restorations which is hardenable at mouth temperature or around 37° C. or more after triturating multicomponent liquid gallium alloy with alloy powder, is disclosed. The mixture has a heterogeneous structure after hardening, and contains as the overall composition, 9-47% gallium, 1-35% indium, 0.2-38% tin and 1-68% silver as indispensable components and one or more elements selected from 0.4-35% palladium, 0.5-25% copper and 0.4-12% zinc as arbitrary components. The multicomponent liquid gallium alloy contains 45-85% gallium, 5-40% indium and 1-30% tin as fundamental components and small amounts one or more elements selected from silver, palladium, gold, platinium, copper, zinc and germanium as arbitrary components. The alloy powder contains 1-85% silver and two or more elements selected from 1-40% tin, 1-40% palladium, 1-30% copper, 1-15% zinc and 1-25% indium. Also, the alloy powder is used with one or more single metal powder selected from palladium, platinium, gold, silver, copper and tin and/or powdered alloy containing one or more of said metals in which said single metal powder and said powdered alloy consist of a spherical or near spherical-irregular particle shape having particle size different from those of said alloy powder or a flat or flaky particle shape.
