Dual-site cationic disorder engineering for ultralow amorphous-like thermal conductivity in thermal barrier coatings

ZWZide WuYCYuning CaoJXJiaxin Xue

Key Points

  • This research aims to explore the effects of dual-site cationic disorder on thermal conductivity in high-entropy pyrochlore oxides.
  • Investigated high-entropy pyrochlore oxides with Y3+ occupancy at A and B sites.
  • Analyzed thermophysical properties and lattice disorder.
  • Tailored the thermal conductivity through material composition adjustments.
  • Induced lattice disorder led to ultralow thermal conductivity values.
  • Thermophysical properties were significantly adjustable based on Y3+ site occupancy.
  • Demonstrated potential for optimized thermal barrier coatings.

Abstract

High-entropy pyrochlore oxides with lattice disorder induced by Y 3+ occupancy at both A and B sites exhibit tailorable thermophysical properties.
