Graphite Solutions for Tomorrow's Innovations
Vibrated graphite has a uniform structure with medium grain size. Besides, it becomes very popular because of its low ash content, enhanced mechanical strength, and good electrical and thermal stability, and is widely used for processing large-scale workpieces. It can also be further strengthened after resin impregnation or anti-oxidation treatment.
It is widely used as a heating & insulation element in the production of polysilicon and monocrystalline silicon furnaces in the photovoltaic industry. It is also widely used in manufacturing heating hoods, heat exchanger components, melting and casting crucibles, construction of n nodes used in electrolytic processes, and manufacturing of crucibles for melting and alloying.

The principle of making vibrated graphite is to fill the mold with a paste-like mixture, and then place a heavy metal plate on top of it. In the next step, the material is compacted by vibrating the mold. Compared with extruded graphite, the graphite formed by vibration has higher isotropy. graphite products are produced by extrusion method.
