Graphite anode
Graphite anode is made into low ash raw material by high temperature graphitizing and ash handling treatment. Mainly used in electrolysis and electroplating industry.
Classification
Classing as geometry is stick and board series, as Physical and chemical indicators is senior and 1st grade.
