Large Size Graphite Block
Our Large Size Graphite Block have high strength, superior shock resistance, resilience to high temperatures, corrosion, strong oxidation resistance, and low resistivity.
Description
The large-sized graphite block (Medium grained) is a type of graphite products with a maximum particle size ranging from 0.8 to 2.0mm. Most of them are formed through vibration molding or extrusion forming. The large-sized graphite is primarily shaped into graphite cylinders and graphite blocks.
Features
It is characterized by its compact and uniform structure, high thermal conductivity, high compressive strength, and long service life.
Applications
Graphite crucible, graphite boat, graphite mold, graphite heat exchanger, etc.
