High-Purity Ultrafine Hafnium Carbide (HfC) Powder
Hafnium carbide (HfC) is an ultra-high-temperature transition-metal carbide with a cubic crystal structure and a grey powder appearance. It is recognized for its exceptionally high melting point (approximately 3,890°C), high hardness, retained strength at elevated temperature, corrosion resistance and relatively low thermal conductivity. These characteristics make HfC a strong candidate for demanding thermal-protection and wear-resistant material systems.
Key Product Advantages
- Ultra-high-temperature capability for severe thermal environments
- High hardness and useful high-temperature mechanical strength
- Good resistance to chemical attack and high-temperature degradation
- Fine, controllable particle size for powder processing and composite formulation
- Suitable for advanced ceramics, coatings and carbide-based composites
Typical Chemical Composition
| Grade | C Total (wt.%) | O max (wt.%) | N max (wt.%) | S max (wt.%) |
|---|---|---|---|---|
| HfC | 6.1–6.3 | 0.30 | 0.10 | 0.02 |
The values above are the typical chemical limits provided for this product. Final acceptance requirements should be confirmed in the technical specification for each order.
Particle Size & Customization
Particle size can be evaluated and adjusted according to the intended forming, sintering, coating or composite process. Please provide the target particle-size range, purity requirements and application conditions when requesting a quotation.
