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 x 103 W/m in both the with-grain and against-grain directions, and the graphite so produced.
L'invention concerne un procédé servant à produire un article en graphite ayant un coefficient de dilatation thermique (CDT) inférieur à environ 2,0 ppm/°C sur une plage de températures allant de 30 °C à 100 °C et un indice d'isotropie inférieur à environ 1,5 et ayant également avantageusement un paramètre de résistance aux chocs thermiques supérieur à environ 150 x 103 W/m à la fois dans la direction des grains et dans la direction perpendiculaire à ceux-ci. L'invention concerne également le graphite ainsi produit.
