Production

● Raw material: high quality petroleum coke & coal tar pitch.

● Vibration-molded or extruded, carbonized and graphitized under precise technical control.

● Usually machined to specific shapes for various purposes.

 

Applications

● Molds: hot pressing molds, static casting molds, centrifugal casting molds, pressure casting

   molds, etc.

● Furnace parts: resistance heating elements, induction susceptors, structural elements and

   charging plates, furnace linings, heat shields and covers for pulling monocrystalline silicon

   or optical fibers, etc.

● Anodes for electrolysis of metals.

● Cathodes in aluminum electrolysis cells.

● Parts for heat exchangers.

● Crucibles for melting and reduction.

● Boats and trays for sintering.

 

Programmable properties

● High thermal and chemical resistance

● Good thermal conductivity

● Low coefficient of thermal expansion

● Minimal wettability to molten metals
