Clay-like composition for sintered precious metal body

Abstract

A clay-like composition for forming a sintered precious metal body, the clay-like composition containing at least a precious metal powder and/or a precious metal alloy powder, an organic binder, an organic additive, and water, wherein the organic additive is from 0.1 to 3.0 mass % of propylene glycol. The clay-like composition has excellent bendability, even after drying during shaping, and as a result, there are minimal time restrictions during working of the composition by bending and the like.

1 . A clay-like composition for forming a sintered precious metal body, the clay-like composition comprising:
 at least a precious metal powder and/or a precious metal alloy powder;   an organic binder;   an organic additive; and   water, wherein   the organic additive is from 0.1 to 3.0 mass % of propylene glycol.   
     
     
         2 . The clay-like composition for forming a sintered precious metal body according to  claim 1 , wherein the organic additive further includes glycerol. 
     
     
         3 . The clay-like composition for forming a sintered precious metal body according to  claim 1 , wherein the organic additive further includes a polyethylene glycol. 
     
     
         4 . The clay-like composition for forming a sintered precious metal body according to  claim 2 , wherein the organic additive further includes a polyethylene glycol.
