Abstract
A liquid alloy thermal paste comprises: a liquid alloy and a trace element, the liquid alloy and the trace element are stirred and reformed to a paste-like liquid alloy mixture that is viscous and does not flow easily, and the liquid alloy mixture is used as the liquid alloy thermal paste.
Claims6
A liquid alloy thermal paste, comprising:
- a liquid alloy including a liquid metal and a plurality of solid metals, the liquid metal including 60 to 80 wt. % of gallium, the plurality of solid metals including 15 to 25 wt. % of indium and 5 to 15 wt. % of tin, the liquid metal and the plurality of solid metals being alloyed or eutecticized by mixing the liquid metal and the plurality of solid metals;
- and
- a trace element, which is 0.01 to 0.5 wt. %, including boron and one or more elements selected from the group consisting of:
- carbon, silicon, germanium, tin and lead of group IVA elements,
- nitrogen, phosphorus, arsenic, antimony and bismuth of group VA elements, and
- selenium and tellurium of group VIA elements,
- wherein by stirring the liquid alloy and the trace element to reform, a viscous and paste alloy mixture is obtained as the liquid alloy thermal paste.

A multi-metal alloy thermal paste, comprising:
- a multi-metal liquid alloy, which is a quaternary liquid alloy or a quintuple liquid alloy, including a liquid metal and a plurality of solid metals, the liquid metal including 60 to 80 wt. % of gallium, the plurality of solid metals including 15 to 25 wt. % of indium, 5 to 15 wt. % of tin, 0.1-10 wt. % of copper and 0.05-5 wt. % of a metal element of group IVA or VA elements, the liquid metal and the plurality of solid metals being alloyed or eutecticized by mixing the liquid metal and the plurality of solid metals;
- and
- a trace element, which is 0.01 to 0.5 wt. %, including boron and one or more elements selected from the group consisting of:
- carbon, silicon, germanium and lead of group IVA elements,
- nitrogen, phosphorus, arsenic and antimony of group VA elements, and
- selenium and tellurium of group VIA elements,
- wherein by reforming the liquid alloy and the trace element, a viscous and paste alloy mixture is obtained as the multi-metal alloy thermal paste.
