Coal pitch as a binder

Abstract

The relation between the properties, composition, and structure of pitch and its modification on carbonization is considered. The basic stages in carbonization are determined, and a step-by-step carbonization model is proposed on the basis of thermal analysis and data regarding the changes in pitch composition and properties. The properties of pitch as a binder must be characterized by two parameters: one characterizing the formation of the blank; and the other characterizing its sintering.
