METHOD FOR PRODUCING CARBON-GRAPHITE ITEMS Russian patent published in 2004 - IPC

Abstract RU 2230380 C2

FIELD: production of carbon-graphite items that can be used in nuclear fuel production and powder metallurgy. SUBSTANCE: method involves procedure of mixing up graphite powder, binder, and fuel microelement. Mixture produced in the process is pre-compressed, then subjected to heat treatment; during heat treatment temperature of items is periodically reduced in phase transition regions by 10 - 15 ^oC, temperature interval between these temperature reduction procedures being chosen between 20 and 30 ^oC. EFFECT: reduced quantity of rejects due to preventing crack development. 1 cl, 2 dwg, t tbl, 6 ex
