ABSTRACT:
Manufacture of coal-tar pitch coke with a predetermined degree of anisotropy of the linear thermal expansion coefficients and thermal volume expansion coefficient by adding primary resin and secondary resin to produce a pitch mixture having primary resin content and secondary resin content to cause on coking of the mixture production of coke having the desired properties of degree of anisotropy and thermal volume expansion coefficient. By the addition of the resins, production of a coal-tar pitch coke with a volume expansion coefficient between approximately 3 .times. 10.sup.-6 and 18 .times. 10.sup.-6 an anisotropy degree of approximately 1.1 to 2.0 may be obtained.
