Abstract

This article examines one possible method of making iron-carbon materials in order to obtain materials with a low content of impurities (especially oxygen) and sufficiently high density. The proposed method is also evaluated from the viewpoint of producing materials with a low carbon content. The technology traditionally used to obtain powder materials is discussed and the prospects for combining the reduction of surface oxides and consolidation of the powder into a dense semifinished product are examined. Powders of graphites obtained by using special synthetic low-ash pitch (SSLG) and high-temperature coaltar pitch (HCP) as the carbon-bearing components (CBC) are employed to achieve the stated objective of this investigation. The shaping method chosen is hot pressing with resistance heating.
