Abstract
1,150,958. Pyrolytic graphite. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 July, 1967 [5 July, 1966], No. 30679/67. Heading C1A. Highly oriented pyrolytic graphite is deposited from a carbon- and hydrogen-containing gas on to a substrate, e.g. electrographite, heated to at least 1800‹ C. but having a lower surface temperature than the gas supplied thereto. The temperature difference may be at least 100‹ C., preferably 200‹ to 500‹ C.; substrate temperature may reach 3200‹ C. Deposition may occur from such gases as CH 4 , CH 2 O, C 3 H 8 and C 6 H 6 , or, in a closed system hydrogen gas may transport carbon from a supply of the element at a higher temperature than the substrate, on which deposition then occurs.
