Tantalcarbid Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
Hard, heavy, refractory, crystalline solid.
Hardness 1800 kg/sq mm, resistivity 30 μΩ?cm (room temperature).
Extremely resistant to chemical action except
at elevated temperature.
Physikalische Eigenschaften
Golden brown crystals, soluble
in HF-HNO mixture. Crucible 3
container for melting ZrO and
similar oxides with high melting
point. Corrosion resistant to
molten metals such as Ta and
Re. Readily corroded by liquid
metals such as Nb, Mo, and Sn.
Burning occurs in pure oxygen
above 800°C. Severe oxidation in
air above 1100–1400°C.
Maximum operating
temperature of 3760°C in helium
Verwenden
A mixture of tantalum carbide (TaC) and graphite is a very hard material and is used to
form the cutting edge of machine tools.
Industrielle Verwendung
Tantalum carbide and tungsten carbide combinedin a matrix of nickel, cobalt, and/or chromiumprovide an RHM formulation especiallysuited for a combination of corrosion and wearresistance. Some grades are almost as corrosionresistant as platinum. Nozzles, orifice plates,and valve components are typical uses.
