Abstract:
Abstract not available for EP0871789 Abstract of corresponding document: WO9726384 The invention relates to amalgamable alloys for low mercury dental amalgam compositions. According to the invention, powders comprising silver and 5 % to 70 % by weight copper, are used as amalgamable alloys for obtaining dental amalgams when mixed with mercury-indium alloys containing up to 82 % by weight indium. Optionally, the alloy compositions additionally contain 0.1 % to 10 % of a noble metal selected from platinum, gold and palladium. According to a preferred embodiment, the average particle size of the powders is in the range of between 10 mu m to about 25 mu m.
