Vibration Graphite
Summary
Vibration Graphite Block is a medium particle (0.8mm-2mm) of high quality large size graphite block. We offer a variety of sizes. Based on our experimental database, we provide our customers with a tailor-made selection of materials to ensure that the needs of their specific application are met.
Features
- High thermal and chemical resistance
- Good thermal conductivity
- Low coefficient of thermal expansion
- Minimal wettability to molten metals
Applications
- Heat treatment: Vacuum furnace, inert atmosphere furnace heating element, conductive electrode and connecting parts, loading tray/plate, muffle box, thermal field lining and structural components, crucible/material box, tooling, mold, etc.
- Metallurgy and casting: degassing stirring rods, rotors, blowing pipes, carbon sleeve rollers for silicon steel annealing furnaces, melting crucibles, casting molds, etc.
- Chemical industry, electrolysis: graphite heat exchanger components, magnesium manganese lead sodium electrolysis anodes (cathodes), etc.
- Photovoltaics: Polycrystalline silicon hydrogen reduction furnace electrodes, heating elements, etc.
- Lithium ion batteries: anode carbonization crucibles, saggers, etc.
- More applications.
