Silicon Metal 421 Lump
In a silicon furnace, the electrode is the heart, an important part of the electrical conduction system. Electric current is fed through the electrode into the furnace to produce an arc, which is used for chemical silicon smelting. Requirements for electrode materials :(1) good conductivity, small resistivity, to reduce power loss. (2) The melting point should be high, the coefficient of thermal expansion should be small, not easy to deformation;
