Product Description:
Our graphite crucibles offer high performance with good technical and economic effect. They are used in metallurgy, casting, chemical and (scientific) industry in general; they are also used to produce metal melting including gold, sliver,coppper, etc.
Features of graphite crucible :
- Fine grain and high density
- Homogeneous structure
- Excellent thermal conductivity
- High mechanical strength
- Proper electrical conductivity
- Minimum wettability to molten metals
- Various sizes machined as per requirements.
