Applications

  • Aerospace and Defense: HfC is used in rocket nozzles, heat shields, and other components exposed to ultra-high temperatures in hypersonic vehicles and spacecraft.

  • Cutting Tools and Coatings: Due to its hardness and wear resistance, HfC is applied as a coating on cutting tools to extend their lifespan and improve performance.

  • Nuclear Technology: HfC is used in nuclear reactors as a material for control rods and as a barrier for nuclear fuel due to its stability under extreme conditions.

  • Ultra-High Temperature Ceramics (UHTCs): HfC is a key component in the production of UHTCs, which are used in environments that experience temperatures above 2000°C.

Hafnium Carbide HfC Powder Reference

Synthesis of Ultra-Fine Hafnium Carbide Powder and its Pressureless Sintering

  • Ultra-fine HfC powders with particle sizes of 380 or 225 nm were synthesized by carbothermal reduction of HfO2 with graphite or carbon black, respectively. The investigation of the process indicated that a vacuum level as high as 5 Pa was appropriate for decreasing the reaction temperature and consequently limiting the particle growth of HfO2 reactant. Type and size distribution of carbon sources demonstrated an obvious effect on the particle size of the HfC powders obtained.
