✦ Synopsis

Thermogravimetric analysis techniques have been adapted to study the thermal decomposition of six coal tar pitches. Two material constants are introduced to describe the thermal stability and/or reactivity of coal tar pitches. These constants can be correlated with the softening point of the pitches. It is also shown that both the temperature where the rate of volatilization is at maximum, (T& and the temperature range where most volatiles are evolved, AT, can also be used to describe the thermal stability of coal tar pitches. The practical importance of T, and AT in determining the proper choice of the baking cycle of green carbon bodies is discussed.
