Specifications
High temp proof: melting point of graphite is 3850 C , boiling point is 4250 C, small loss even under high temp burning.

1. High purity graphite has its unique advantages: low resistivity, high temp proof, anti corrosion, good thermal shock resistance, electrical conductivity, low coefficient of thermal expansion, self -lubricating, suitable for precise process.
2. Electrical conductivity, thermal conductivity: electrical conductivity of graphite is 100 times than normal nonmetal metal minerals, even better than that of steel, iron, aluminium, lead etc. Coefficient of thermal conductivity decreases as temp increases, graphite is even going to be a heat insulator under extremely high temp. Graphite can conduct electricity due to each carbon atoms in graphite can only form three covalent bond with other carbon atoms, each carbon atoms remains a free electrons to transmit electric charge.
