    摘要: A method for producing a 100% mesophase composed only of Q.I. component and Q.S. component is provided. This method comprises forming mesophase by the heat treatment of petroleum-origin pitch, subjecting the heat-formed pitch to a condition of heating under quiescent state to cause only the mesophase in the heat-formed pitch to grow and coalesce, separating only the non-mesophase of the upper layer and repeating the operation of the heat treatment and maintenance of heating under a quiescent state by the separated non-mesophase, as a raw material.
