The graphite blocks are made from the low ash petroleum coke and its C content is above 99%.After milling, screening, dosing,kneading,vibrated molding, pitch impregnation,baking and high temperature graphitization,our high pure blocks all meet the standard JB/T 2750-2006.
1.High temperature resistance:The graphite is one of the best material resistant to the high temperature.Its melting point is 3850cu00b150c,boiling point can be up to 4250c.In the high temperature 7000c for 10S,the graphite material lose least,so,it is with the great ability to high temperature.
2.Special thermal shock resistance:When the temperature changed suddenly,because of the small CTE,the graphite has the better thermal stability.
3.Thermal and electrical conductivity:about four times better than the stainless steel,100 times better than the general non-metal.
5.Good chemical stability:In the normal temperature, the graphite material has the good chemical stability and can afford the corrosion of the acid, alkali and organic solvent.
