Synthesis of Niobium Carbide from Niobium Oxide Aerogels

Chemistry of Materials, 1995
Niobium carbide (NbC) synthesis was studied by the temperature-programmed reaction (TPR) between niobium oxide precursors of different textural properties and a 20% (v/v) CH{sub 4}-H{sub 2} mixture. Surface areas ranging between 13 and 74 m{sup 2}/g were obtained depending on the temperature and on the nature of the precursor (Nb{sub 2}O{sub 5} or an ...

Hardness anisotropy in niobium carbide

Journal of Materials Science, 1974
Measurements of hardness anisotropy by Knoop diamond indentation on the {100} surfaces of Nb6C5 crystals show that the hardness is determined by crystallographic slip on {111} 〈1¯10〉 and {110} 〈1¯10〉 systems. {111} is the preferred slip plane for Nb6C5 and crystals with higher carbon content which show a marked decrease in Knoop hardness.
