Semi-graphitic Cathode Carbon Block

Semi-graphitic Cathode Carbon Block is made of high quality and high temperature 1800 centigrade electrical calcined anthracite,graphite particle as raw material,pitch as binder,through forming,and baking under temperature 1350 centigrade. It acts as both electrical conductive material and lining material in electrolyzer.It features high resistance to high temperature,erosion and termal shock,good electrical and thermal conductivity.It is helpful of saving energy, increasing current efficiency and prolonging service life.
