Key Advantages of Zhiyue’s HfN Powder

Industrial Applications of HfN Powder

HfN powder is a critical material in demanding environments where high thermal, mechanical, and chemical performance is essential:

• Thermal Barrier and Erosion-Resistant Coatings
  Used in aerospace components, rocket nozzles, and turbine parts exposed to oxidizing and high-velocity flows.

• Ultra-High Temperature Ceramics (UHTCs)
  Combined with SiC or ZrB₂ to fabricate structural components capable of withstanding temperatures above 2000 °C.

• Semiconductor & Microelectronic Devices
  Functions as a diffusion barrier, hard mask, or conductive layer in CMOS, RF, or MEMS devices.

• PVD Sputtering & Target Fabrication
  Base material for producing HfN sputtering targets used in hard coatings, wear-resistant films, and microelectronic layers.

Key Considerations for Purchasing HfN Powder

1. Purity Requirements

• ≥99.9% recommended for electronic and thin-film deposition use.

• ≥99.5% suitable for structural ceramics, refractories, and composite reinforcement.

2. Particle Size Distribution

• Fine powder (<5 μm) supports better sinterability and coating uniformity.

• Nano-scale hfn powder offers enhanced surface reactivity for specialized coatings or research.

3. Phase Stability & Crystal Structure

• Zhiyue ensures stable FCC phase through optimized synthesis to maintain performance in high-temperature environments.

4. Storage and Packaging

• HfN is stable in inert conditions but can gradually oxidize when exposed to moisture or air.

• All batches are packaged in vacuum-sealed or argon-purged containers with full traceability.
