Jinnai Carbon

Cathode Carbon Block

1 Cathode Carbon Block is made of anthracite as main raw material,pitch as binder,through forming,baking and machining.

2 Semi-graphitic Cathode Carbon Block is made of high quality and high temperature Electrical Calcined Anthracite(ECA),Graphite Particle(GP) as       raw material,pitch as binder,through forming,baking and machining.

3 Graphitic Cathode Carbon Block is made of graphite particle as main raw material,pitch as binder,through forming,baking and machining.

4 Graphitized Cathode Carbon Block is made of petroleum coke as raw material,pitch as binder,through forming,baking,impregnation,

   re-baking,graphitization and machining.
