Production
Raw material: high quality petroleum coke & coal tar pitch.
Vibration-molded, carbonized and graphitized under precise technical control.
Usually machined to specific shapes for various purposes.
Applications
1. Molds: hot pressing molds, static casting molds, centrifugal casting molds, pressure casting molds, etc.
2. 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.
3. Anodes for electrolysis of metals.
4. Cathodes in aluminum electrolysis cells.
5. Parts for heat exchangers.
6. Crucibles for melting and reduction.
7. Boats and trays for sintering.
Programmable properties
Medium-grained, uniform and dense structure
High thermal and chemical resistance
Good thermal conductivity
Low coefficient of thermal expansion
Minimal wettability to molten metals
