First claim
Opening claim text (preview).
The invention claimed is: 1. A composition for forming a sintered silver-copper alloy body comprising: a powder constituent consisting essentially of silver powder and copper oxide powder; a binder; and water, wherein the copper oxide powder consists of copper (II) oxide powder (CuO) and copper (I) oxide powder (Cu 2 O), the amount of the copper (II) oxide powder (CuO) is from 4 mass % to 35 mass % with respect to the amount of the powder constituent, the total amount of the copper (II) oxide powder (CuO) and copper (I) oxide powder (Cu 2 O) is 54 mass % or less with respect to the amount of the powder constituent, and the amount of silver in the silver powder is from 46 mass % to 97 mass % with respect to the amount of the entire metal elements in the powder consistent. 2. A composition for forming a sintered silver-copper alloy body according to claim 1 , wherein the composition includes the binder and the water in the range of from 5 mass % to 30 mass %. 3. A sintered silver alloy body obtained by firing the composition for forming a sintered silver-copper alloy body according to claim 1 . 4. A sintered silver alloy body obtained by firing the composition for forming a sintered silver-copper alloy body according to claim 2 . 5. A composition for forming a sintered silver-copper alloy body according to claim 1 , wherein the composition further includes at least one of fatty substance and surface active agent. 6. A composition for forming a sintered silver-copper alloy body according to claim 5 , wherein the fatty substance includes at least one of organic acids, organic acid esters, higher alcohols, and polyhydric alcohols.
