Niobium Carbide
Catalog NO.: TFCBFC-0047 Category: Carbide
We provide niobium carbide (NbC) powder, a hard refractory carbide known for its high melting point (~3600°C) and excellent electrical conductivity. It is widely used as a grain refiner in cemented carbides and as a component in superconductive materials. Our product features high phase purity and low impurity levels.
| Chemical Formula | NbC |
| Storage | This product should be stored in a sealed container within a cool, dry environment. It should not be exposed to the air for prolonged periods, as moisture absorption may lead to agglomeration, thereby compromising its dispersion properties and performance. Additionally, the product should be protected from heavy pressure and kept away from oxidizing agents. |
◈ Multiple Particle Sizes: Nano, sub-micron, micron grades.
◈ Chemical & Thermal Stability: Excellent stability under extreme conditions.
Cemented Carbides & Superhard Materials: Additive in WC-C-NbC ternary alloys, extending tool life 30–50%. At 15–20 wt% NbC, HRA ≥92 for mold coatings and cutting tools.
High-Temperature & Refractory Parts: NbC ceramics and NbC-WC-C systems used for aerospace nozzle throats, rocket engine nozzle coatings (stable in extreme heat/corrosion).
Wear & Corrosion Resistant Products: High hardness and wear resistance make it key for abrasives, cutting tools, and wear coatings.
Electronics & Optoelectronics: Electron emission materials, IC packaging (thermal conductivity + electrical insulation).
Other Uses: Chromium-free special alloys, engineering ceramics, purple synthetic gemstones, raw material for Mo2C production.
