Popis: Silicided graphites, prepared by SGP technology, using a graphite nanofiller fraction of less than 100 μm, are promising materials no worse in properties than leading analogs of overseas firms. Nonetheless, in view of the available raw material base for carbon materials rapid evaluation methods are required for the quality of graphites used in the manufacture of silicided objects based on them. Volumetric reaction makes it possible to establish quite rapidly the suitability of test carbon material for manufacturing silicided objects based on them without recourse to compaction, firing, machining, and siliciding shaped objects. X-ray structural data for the degree of graphitization of carbon material γ, and also a change in its structural characteristics (La and Lc) during reaction with silicon may be additional criteria for the choice of graphite filler.
