Abstract

FIELD: technology of carbon-graphite materials. SUBSTANCE: dispersed graphite- containing wastes with iron content of 10-60 mas. are treated with concentrated sulfuric acid with oxidizer (KCrO), washed, dried and subjected to heat treatment for expansion in medium of reducing gas (CH,, COor H) at 500-1100 C. EFFECT: reduced corrosivity of reaction products (gas atmosphere and expanded graphite) and improved magnetic properties. 3 cl, 2 tbl
