High purity graphite block for mold industry
Graphite Block
Vibration-molded,Isostatic or extruded, carbonized and graphitized under precise technical control.
High thermal and chemical resistance
Applications
1. Molds: hot pressing molds, static casting molds, centrifugal casting molds,
pressure casting molds, fused refractory 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 the 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
1. High thermal and chemical resistance
2. Good thermal conductivity
3. Low coefficient of thermal expansion
4. Minimal wettability to molten metals
