1、 Definition of Liquid Thermal Conductive Materials

Liquid thermal conductive material refers to a material that is in a liquid state at high temperatures and has high thermal conductivity. It can quickly transfer heat at high temperatures and is widely used in various industrial fields. Liquid thermal conductive materials are usually liquid metals such as mercury, sodium, lead, etc.

2、 Properties of Liquid Thermal Conductive Materials

1. Good thermal conductivity. Liquid thermal conductive materials have high thermal conductivity and can quickly transfer heat at high temperatures. The thermal conductivity of liquid thermal conductive materials is usually above 100W/mK, which is several times or even tens of times that of ordinary metals.

2. Good stability: Liquid thermal conductive materials have good stability at high temperatures and are not easily oxidized, corroded, or deteriorated. This allows it to be used for a long time at high temperatures without affecting its thermal conductivity.

3. The density of liquid thermal conductive materials is usually higher than that of ordinary liquids, which allows them to withstand greater pressure and weight at high temperatures.

4. The specific heat capacity of liquid thermal conductive materials is usually smaller than that of ordinary liquids, which means that they can quickly heat up and cool down in a short period of time, making them suitable for industrial fields that require rapid heating and cooling.

3、 Preparation method of liquid thermal conductive material

The preparation method of liquid thermal conductive materials is usually achieved through chemical or electrolytic reactions at high temperatures. Among them, electrolytic reaction is one of the most commonly used preparation methods. Taking liquid sodium as an example, the preparation method of liquid sodium is as follows:

1. Place high-purity sodium salts (such as sodium chloride) into the electrolytic cell.

2. Add an appropriate amount of liquid barium to the electrolytic cell to improve electrolysis efficiency.

3. Reduce sodium ions to sodium metal through electrolytic reaction.

4. Remove the generated liquid sodium from the electrolytic cell for refining and purification.

4、 Application Fields of Liquid Thermal Conductive Materials

Liquid thermal conductive materials are widely used in various industrial fields, such as nuclear energy, aerospace, power, chemical industry, etc.

1. Liquid thermal conductive materials in the field of nuclear energy are used as coolant and heat transfer medium in nuclear reactors, which can effectively transfer the heat generated by nuclear reactors and ensure the safe operation of nuclear reactors.

2. Liquid thermal conductive materials are used as heat transfer media in the aerospace industry, which can transfer the high temperature generated by the engine and ensure its normal operation.
