The electrode materials we use generally have many physical and chemical properties. For example, the conductivity should be good, the resistivity should be small to increase the power of the molten pool; then the melting point should be high; and the thermal expansion coefficient should be small, when the temperature changes suddenly, it is not

Graphite is a crystal. Graphite is a kind of transition crystal between atomic crystal, metal crystal and molecular crystal.   In the crystal, the covalent bond is formed by SP2 hybridization between the carbon atoms in the same layer. Each carbon atom is connected with the other three carbon atoms. Six carbon atoms form regular

Carbon electrode is a conductive material made of anthracite and metallurgical coke. The specific resistance of carbon electrode is 2 ~ 3 times larger than that of graphitized electrode, and its compressive strength at room temperature is larger than that of graphitized electrode, but its thermal conductivity and oxidation resistance are not as good as

The full name of International Women’s Day (IWD) is United Nations women’s rights and international peace day. In China, IWD is also known as international working women’s day, March 8 and March 8 women’s day. It is a festival set up on March 8 every year to celebrate Women’s important contributions and great achievements in

The first month is the first month of the lunar calendar. The ancients called “night” as “Xiao”. The fifteenth day of the first month is the first full moon night of the year, so the fifteenth day of the first month is called “Lantern Festival”. According to the Taoist “Sanyuan”, the 15th day of the

Anode graphite plate, also known as graphite positive plate and graphite positive rod, has excellent characteristics of high temperature resistance, good electrical and thermal conductivity, easy machining and good chemical stability. It is widely used in the production of chlorine by electrolysis of aqueous solution, alkali by electrolysis of salt solution, and various metallic and
