METHOD OF PREPARING GRAPHITE-CONTAINING COMPOSITIONS Russian patent published in 2000 - IPC

Abstract RU 2160290 C1

FIELD: carbon materials. SUBSTANCE: graphite-containing composition for biological protection against neutron radiation is prepared by mixing artificial dusty (particle size not exceeding 90 mcm) graphite with granulated polypropylene in ball drum mixture at weight ratio of balls to composition from 3: 1 to 6:1, after which mixture is extruded. EFFECT: enabled manufacturing defectless products with graphite distribution uniformity within 5% and thereby increased neutron protection. 1 tbl, 11 ex
