Abstract : This report describes the mechanical and thermal properties of several types of ZT graphite. Grade ZTA is discussed in detail and its physical properties are compared to those of other premium graphites, including pyrolytic, over the range from room temperature to 3000 C. Specifications for Grade ZTA are established. The properties of other grades of ZT graphite and the results from 70 subscale firings in solid fuel rocket motors at various locations ar tabulated.
