Key Advantages of Zhiyue’s Zirconium Carbide Powder

Where Is Zirconium Carbide (CAS 12070-14-3) Commonly Used?

ZrC powder plays a critical role in advanced material systems operating in aggressive conditions:

• Thermal Protection Systems (TPS)
  Used in reentry vehicles, rocket engines, and hypersonic aerospace platforms due to its exceptional thermal shock resistance.

• Hard Coating & Surface Engineering
  Serves as a base material for plasma-sprayed coatings or PVD films on cutting tools, wear parts, and molds.

• Nuclear Fuel Cladding & Control Rods
  Investigated as an inert matrix for nuclear fuel due to low neutron absorption and high chemical stability.

• High-Temperature Structural Ceramics
  Blended with SiC or ZrB₂ to form UHTCs for turbine blades, jet nozzles, or thermal barrier systems.

• Electronic & Electrochemical Applications
  Utilized in field emission cathodes, electrodes, and thermionic emission systems thanks to its good conductivity.

Key Considerations When Purchasing ZrC Powder

1. Purity Level

• ≥99.9% is essential for nuclear, electronic, and thin film applications.

• 99.5% is sufficient for most thermal spray, composite, or mechanical applications.

2. Particle Size Distribution

• Submicron and nano-sized powders (<1 µm) support faster sintering and finer coating microstructures.

• 1–10 µm range is optimal for most additive manufacturing, pressing, and sintering applications.

3. Thermal Stability and Atmosphere Compatibility

• ZrC performs well in vacuum, inert, and reducing environments.

• In oxidizing atmospheres above 800–1000 °C, a protective layer or ZrC-SiC hybrid is recommended.

4. Packaging and Storage

• ZrC is sensitive to surface oxidation over time; our packaging minimizes air exposure with vacuum sealing or argon gas flushing.
