Abstract
A process for producing a graphite article having a CTE of less than about 2.0 ppm/° C. over the temperature range of from 30° C. to 100° C. and an isotropy ratio of less than about 1.5 also advantageously having a thermal shock resistance parameter of greater than about 150×103 W/m in both the with-grain and against-grain directions, and the graphite so produced.
