Niobium carbide powder Density :7.56g/cm3, melting point : 3490°C…etc. Niobium carbide powder is brown-gray metallic powder with purple lustre．The powder have the properties of high melting point ,high hardness ,high chemical stability , it is applied in the field of high temperature refractory material and cemented carbide products.

Application:

1: it is normally worked as additive in cemented carbide product, from WC-Nbc-C solid solution.

2: May also make the purple artificial jewel.

3. Together with the tungsten carbide powder and Molybdeum carbide powder, Niobium carbide powder is used as additive in the field of spray coating material, welding powder material, such as hot forging die, the cutting tool, the jet engine turbine blade, the valve, the tail skirt and the rocket spray nozzle coating.

Niobium carbide powder in size 40-60mesh (250-380um), 60-80mesh (180-250um), 80-100mesh (150-180um), 100-150 mesh(106-150um), 150-200mesh (75-106um), 200-400mesh (38-75um), 200-325mesh (45-75um), -325mesh (-45um ), -400mesh (-38um) is usually be used in the field of high heat resitance thermal sparay coating ;
