れて来た。Amalgam, which is a mixture of mercury and silver alloy powder, has been used as a dental filling material for many years. That is, the amalgam obtained by mixing and kneading a predetermined amount of mercury, which is a liquid metal, and a silver thread alloy powder with one predetermined composition, is filled into the cavity of a patient's tooth, and after filling, the alloying reaction progresses. It hardens to withstand occlusion, and compared to other double-layer alloys for casting, it has a semi-(II)
It has been used in its current size because of its good workability in terms of fi and handling.

a t''! Binary alloys such as monolithic or Ga-based eutectic alloys such as Ga-8n eutectic alloys, Ga-Inn eutectic alloys, and Ga-Zn eutectic alloys, or combinations thereof, are used, and the metal powder is Au, A lot of basic research has been carried out using powders of single metals such as Ag, Co, Sn, and Zn, or powders of alloys such as Au alloys and Ag alloys, targeting mixed materials made by combining these liquid metals and metal powders. ing. However, compared to mercury-based amalgam, various properties such as handling and utility for biphasic repair are still inadequate, and it has not been put into practical use.

After sieving through a predetermined sieve, the mixture was heat-treated and adjusted. The amount of liquid metal is adjusted so that when a predetermined amount of this alloy powder is mechanically kneaded with an amalgam-based kneaded material for about 10 seconds, a kneaded product having approximately the same plasticity as a conventional amalgam-based kneaded product is obtained. For the kneaded product obtained by mixing these, scientific and engineering properties such as diametral tensile strength, dimensional change, creep, etc. were measured in accordance with the test method of JTST6109.
