Abstract
The present invention provides carbonized pitch articles and methods for producing the same. Synthetic mesophase pitch is mixed with partially anisotropic pitch, which may be selected from heat-soaked isotropic pitch and heat-soaked mixtures of isotropic pitch and mesophase pitch. In producing carbon moldings, the mesophase pitch is first stabilized to make it at least partially infusible, prior to mixing. In producing carbon fibers, the mesophase pitch will not typically be stabilized before mixing, rather, the resultant pitch fiber, produced from the mixture, will be stabilized by oxidation and air. The resultant fibers and moldings are carbonized according to conventional methods.
