<p>PROBLEM TO BE SOLVED: To solve problems for example, in a sinter Au material and a sinter Au alloy material, when they are sinter bodies as ornament materials, they must be subjected to ornament processing as post processing, for acquiring glossiness as a jewel.SOLUTION: The invention is characterized in that: 50-99.9 mass% of Au powders whose grain diameter is 1μm-200μm and 0.1-50 mass% of Au powders whose grain diameter is 0.1μm-0.5μm are blended; and the blended powders are molded and sintered.</p> |
