What is Vibration Graphite?

Vibration graphite is manufactured by compacting graphite powder using vibration molding, resulting in homogeneous structure, large-size blocks, and fine mechanical strength. The properties of vibration graphite can be further improved by:

Resin impregnation
Anti-oxidation treatment

Applications

Vibration graphite is widely used in:

Photovoltaic industry (e.g. polycrystalline silicon production)
Monocrystalline silicon furnace insulation and heating components
Casting molds, ceramics, and refractory applications
Non-ferrous metal smelting
Chemical processing equipment
Electronics, EDM, metallurgy

Key Features

Uniform fine structure
Excellent thermal & electrical conductivity
High strength and oxidation resistance
Stable in extreme temperature conditions
Available in large block sizes
