貴金属粘土の開発

Abstract

Precious Metals Plasticine (PMP), a mixture of precious metal powder and organic binder, has been developed. By using it, various shapes of precious metals can be made easily by hand forming, just as with paper clay or potter's clay. The dried PMP can be carved just as gypsum or plaster of Paris. Hollow parts can be also made from the clay using a clayey core material. PMP sheet has also been developed by changing the composition of binder, and it can be folded into figure. In this paper, the manufacturing processes and properties of PMP is described and some applications are introduced.
