Abstract

Furfuryl alcohol containing a polymerization catalyst is used as carbonisable binder in admixture with powdered carbon to form a graphite body or as a carbonisable impregnant to increase the density of a preformed graphite body. The furfuryl alcohol may be used first to form a graphite article and then to increase its density. The catalyst may be maleic anhydride, sulphamic acid, nitric acid, oxalic acid, sodium, potassium or cupric nitrate, or uranyl nitrate hexahydrate. The latter catalyst produces a "loaded" article for use in nuclear reactors. UO2, U3O8, or UO3\t may be incorporated in the graphitisable mixture to produce a uranium loading of up to 1.5 gm./c.c. The carbon may be in the form of raw or calcined coke or graphite flour or furnace, thermal, or lamp black. The coke or graphite may have been formed from furfuryl alcohol. The graphitisable mixture may be extruded or pressed to form a shaped "green" body. In the former case the mixture may contain methyl cellulose. The green body may be of laminar construction, at least one layer being loaded. The green body may be graphitised entirely under pressure or up to the end of the curing step only. The graphite article may have an apparent density of 1.28-1.57 gm./c.c. and a fibre stress of 2780-3200 p.s.i. Examples are given.
