Tantalcarbid Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften

Hard, heavy, refractory, crystalline solid. Hardness 1800 kg/sq mm, resistivity 30 μΩcm (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.
