A study on the high temperature reaction of niobium pentoxide with niobium carbide and titanium carbide

Materials Research Bulletin, 1979
Abstract The high temperature reaction of niobium pentoxide with niobium carbide and titanium carbide has been studied to investigate the feasibility of direct preparation of NbTi alloys and the titanium deoxidation tendency of niobium. Starting with oxide-carbide charges with o:c mole ratio varying from 1.01 to 1.10 and titanium content varying from

Niobium carbide heaters used in growing silicon carbide single crystals

Soviet Powder Metallurgy and Metal Ceramics, 1986
Silicon carbide single crystals can be grown by sublimation by using a furnace with niobium carbide heaters. The working life of these heaters is much greater than that of graphite ones. The crystals are suitable for making light-emitting diodes.

Synthesis of niobium carbides in copper melts

Russian Metallurgy (Metally), 2010
The production of cast composite Cu-NbC alloys by synthesizing of niobium carbides in a copper melt is studied. The processes of carbide formation are intensified by the mechanical activation of niobium and graphite powders, which are mixed with a copper melt, in a high-speed ball mill and by the action of low-frequency vibrations on copper melts.

Properties of zirconium carbide -niobium carbide alloys in their homogeneity region

Soviet Powder Metallurgy and Metal Ceramics, 1971
1. A study was made of the electrical resistivity, thermo-emf, Hall coefficient, magnetic susceptibility, and temperature dependence of electrical resistivity and thermo-emf (at 50–1000°C) of binary solid solutions of zirconium and niobium carbides in their homogeneity region (C/Me =0.9–1.0). 2.
