Abstract

This invention relates to electroconductive liquid alloy, the design and method for preparing the room temperature liquid and electroconductive alloy GalnSn and GalnSnAg. A metal with its purity being greater than 99.99% is selected and thein is smelted to produce the main alloy Galn. And then, Sn(or Sn and Ag) is (are) added into above mentioned Galn to produce GalnSn or GalnSnAg alloy. The product can be used in fields such as: oral surgery, electronics material and refrigeration system.

Description

1. Technical field [0001] The invention relates to a conductive liquid alloy and a preparation method thereof, belonging to the field of special alloy manufacturing. 2. Background technology [0002] With the advancement of material preparation and detection technology, the excellent properties of materials with liquid structure have also been applied. At present, only Hg and Ga can exist in a liquid state and be practically used at room temperature around 20°C. Among the two, Hg has a wide range of applications and a considerable amount; however, Hg has serious pollution and toxicity to the environment and human health. With social progress and scientific development, people have gradually stayed away from it. [0003] In the late 1990s, it was reported that a GaInSn alloy was prepared with a melting point of about 10°C. It was very stable and non-toxic to the human body. Therefore, people used it to replace Hg to make a Ga-alloy filling agent for dental prosthetics. . ...
