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
