Method for manufacturing fusible metal alloy particles with the controlled compositions and melting temperatures and low percolation composites including the fusible metal alloy particles and manufacturing method thereof

摘要

A method of manufacturing a low melting point alloy particle having a controlled composition and melting point, and a low percolation composite using the low melting point alloy particle manufactured thereby, and a manufacturing method thereof are provided. The method for producing the low melting point alloy particles includes: heating a mixture including a continuous medium and two or more metals to melt the two or more metals in the medium; Forming low melting point alloy particles while homogenizing the result of the melting step; And cooling the low melting point alloy particles and separating them from the medium. By the above production method, the metal is melted and homogenized in a continuous medium to produce a small-sized low-melting-point alloy particle having a controlled composition and melting point. When the low-melting-point alloy particles are mixed with non-metallic particles such as polymers and hot press-molded, since they are located at the interface of the non-metallic particles and melted, a low percolation composite having efficient electrical and thermal conduction properties at the interface can be easily manufactured .
