According to the comprehensive performance data of the material and the actual situation of dac-cell experiment, platinum rhodium is the best material for heating wire; Platinum can also be used; Tungsten and rhenium take the second place; Tungsten is next. The higher the price, the better.

The platinum rhodium wire can work normally in high oxygen atmosphere. Considering the heat resistance of the press and anvil, it is necessary to cooperate with water cooling and necessary environmental atmosphere protection in the experiment, which can reach 1500K and can be repeated for many times without burning.

Considering the oxidation brittleness of tungsten rhenium wires and tungsten wires, it is suggested that they should be used in combination with water cooling and necessary environmental atmosphere protection or vacuum environment. They can reach 1800K and can be repeated for many times without burning.

Considering the oxidation brittleness of nickel chromium wire, it is suggested that the nickel chromium wire should be used in combination with water cooling and necessary environmental protection or vacuum environment. It can be used up to 1000k and repeated for many times without breaking.
