Abstract: In order to obtain the optimal properties of special graphite products，the effects of three kinds of special graphite production processes on the thermal expansion coefficient，resistivity，flexural strength and compressive strength of the products were studied experimentally，and the optimal graphitiza⁃ tion heating system of "one soaking，two baking and graphitization" was determined. The results showed that the thermal and mechanical properties of the product are the best under the condition of heating proce⁃ dure 2 and the maximum temperature of 2 810 ℃. The density，flexural strength，resistivity，thermal ex⁃ pansion coefficient and anisotropy of the final product of "one dip，two bake and two graphitization" and "two dip，three bake and graphitization" process are larger，that is，the mechanical properties of the prod⁃ uct are improved，but the thermal properties are reduced.

Key words: special graphite, graphitization, heating rate, graphitization temperature
