Problems solved by technology

[0004] Currently widely used low melting point metals have a minimum melting point of around 8°C and cannot be used in an environment lower than this melting point
Some researchers have also developed liquid metal products with a lower melting point of about 3°C, such as the Chinese patent application number 201410268984.1 titled "A Low Melting Point Liquid Metal and

Embodiment

[0029] Prepare the liquid metal according to the element composition and percentage content in the table below, and test the melting point and heat transfer coefficient of the liquid metal after preparation.

[0030] The preparation process is as follows:

[0031] Step 1, the alloy raw material is selected from an alloy powder raw material with a purity greater than 99.9%, and the alloy raw material is weighed according to the formula;

[0032] Step 2: mix the alloy raw materials except gallium evenly in the preparation container, heat over 200°C, then pour metal gallium into it, heat to 255°C, until the raw materials are fully melted and mixed;

[0033] Step 3: Stir the alloy raw materials in Step 2 evenly, keep it warm for 2.5 hours, and then naturally cool to room temperature to obtain the required liquid metal.

Abstract

The invention discloses a novel liquid metal which is composed of the following components in percentage by mass: 59-68% of gallium, 19-25% of indium, 10-14% of tin and 0.5-3% of bismuth quaternary alloy. The novel liquid metal can also comprise 0.4-1.5 wt% of magnesium, niobium or antimony. By improving the composition of the gallium-base liquid metal, the invention provides a low-melting-point novel liquid metal. The liquid metal has the advantages of fewer alloy components and stable microstructure, effectively avoids the aberration probability in the microstructure, and can be used as a high-efficiency heat dissipation material in heat dissipation products.

Description

technical field [0001] The invention relates to a liquid metal, in particular to an alloy with a low melting point and in a liquid state at normal temperature, a preparation method and application thereof. Background technique [0002] Low-melting-point alloys refer to fusible alloys with a melting point lower than that of ordinary ferrous metals. They also usually refer to alloys with a melting point lower than that of tin at 232°C. They are usually composed of metal elements with low melting points such as bismuth, tin, lead, and indium. When these elements with lower melting points are combined in different proportions, alloys with lower melting points can be obtained. Low melting point alloys also have excellent properties such as low vapor pressure, good thermal conductivity, easy processing, high fluidity, and reusability. Liquid metal is a low-melting-point alloy that is liquid at room temperature, that is, it can flow freely like water at room temperature, but it ha...
