“…Tantalum carbide, TaC, is a refractory carbide with one of the highest known melting points (3985°C) and is considered as an ultrahigh temperature ceramic, UHTC (Andersson et al ., ; Tulhoff, ). There are several subcarbides of the Ta–C system with lower carbon contents; however, the monocarbide, TaC, is the most widely used phase.…”

“…There are several subcarbides of the Ta–C system with lower carbon contents; however, the monocarbide, TaC, is the most widely used phase. Its main application is in cemented carbide as its addition improves the high‐temperature fatigue strength, thermal shock resistance, hot hardness and resistance against cratering and oxidation (Andersson et al ., ; Tulhoff, ). TaC is a potential candidate for ultra‐high temperature applications such as leading edges and nose caps for hypersonic vehicles, rocket thrusters, combustor linings, etc., because of its high melting point.…”

Summary Tantalum carbide samples have been subjected to high‐temperature testing at ∼2300°C using an oxyacetylene torch to evaluate their potential for ultra‐high temperature applications. While large samples cracked during the rapid heating, indicating their inability to withstand thermal shock, small samples survived the severe test conditions. The oxidation products formed were characterized and found to comprise different phases of Ta2O5. The ultra‐high temperature experienced by the samples resulted in the formation of many interesting microstructures, including the formation of submicron sized grains, which has not been reported previously in the literature, as well as the expected evidence of melting.

“…Its mechanical properties nearly match with human bone [34]. It is highly inert, corrosion resistant and having very good biocompatibility [35,36]. It brings the YM of the implant closer to the human bone which makes it suitable by human body tissues [37].…”

Thin amorphous tantalum films are prepared on Si(111) substrates in a metallic glassy state. The amorphous monoatomic state of the film is characterized by X‐ray diffraction studies. The glassy state leads to a negative temperature coefficient of the resistivity (TCR) for low sample temperatures <200 K which is attributed to incipient localization. Above 200 K a positive TCR is observed as expected for a normal Boltzmann transport regime. Upon heating the Si substrate to 1200 K TaSi2 is formed out of the amorphous tantalum film and the silicon substrate. The TaSi2 layer is crystalline as evident from X‐ray diffraction data.magnified imageSchematic drawing of the evaporation setup on either glass or silicon samples.
