摘要： PURPOSE: To obtain inexpensively coke for isotropic carbon materia l, which has fine optical anisotropic tissue, by adding a high-molecular material contg. hydroxyl groups to a bituminous substance such as coal tar pitch, oxidizing the mixture and carbonizing the oxidized product.
CONSTITUTION: 10W50wt% high-molecular material contg. hydroxyl groups such as still residue pitch of phenols or phenolic resin is added to a bituminous substance such as coal tar pitch or petroleum asphalt. The mixture is molten by heating it at 200W400°C, and oxidized, e.g., by introducing an oxidizing gas (e.g. air). The oxidized mixture is carbonizedd at 550W600°C in an inert atmosphere to obtain the desired coke for isotropic material. The resulting coke is crushed and mixed with a binder. The mixture is briqutted, fired and graphitized to obtain an isotropic high-density graphite material.

摘要： PURPOSE:To reduce the puffing of a graphite electrode by keeping within the specified range of temps. for specified hours, and then increasing the temp. immediately without cooling in the manufacture of an artificial graphite electrode by using easily graphitizable coke as the starting material. CONSTITUTION:The artificial graphite electrode is manufactured by using easily graphitizable coke produced from coal-tar pitch as the starting material. At this time, the coke is kept at 1,400-1,700 deg.C for >=0.5hr. Then the temp. is increased directly without cooling to graphitize. The nitrogen which is the primary cause of the puffing is removed in this way, and the puffing can be reduced.

摘要： PURPOSE: A specific aza compound is added to coaltar pitch and heat-treated at a certain temperature to produce a pitch of high carbonization yield in a shortened heat-treatment time.
CONSTITUTION: Coaltar pitch is combined with 1W30wt% of an aza compound with two or more ring structure on the pitch basis and they are heat-treated at 200W500°C. As an aza compound, a residual after quinoxaline is used, because it contains more than 70wt% of aza compounds.

摘要： PURPOSE: To increase the bulk density and improve the strength of an artificial graphite electrode prepared from a coal tar-based needle coke, by carrying out the graphitization in the presence of a specific antipuffing agent.
CONSTITUTION: Metallic nickel, nicket compound (e.g. nicket oxide), metallic cobalt and/or cobalt compound (e.g. cobalt oxide) is used as the antipuffing agent of the present invention. The agent preferably contains ≤25wt% particles having diameter of ≤2.4μ and has an average particle diameter of ≤1.8μ. In the production of a graphite electrode, the above antipuffing agent is added to a coal tar-based needle coke (sulfur content: about 0.05W0.3%, nitrogen content: about 0.3W0.6%). The amount of the agent is about 0.1W1wt% based on the sum of the coke and a binder. The mixture is subjected successively to the forming, primary calcination, impregnation, secondary calcination, and graphitization to obtain the objective artificial graphite electrode.
