Effect of the Pulse Laser Radiation on the Stabilization of the ZrO₂ and HFO₂ High-Temperature Phases

Abstract:

The conditions of formation of the ZrO₂ and HfO₂ high-temperature (tetragonal and cubic) phases in the ablated nanoparticles were investigated. X-ray diffraction and transmission electron microscopy data demonstrate that laser intensities above 10⁹ W/m² ensure the formation of the ZrO₂ high-temperature phases, while intensities above 5·10⁹ W/m² do the formation of the HfO₂ high-temperature phases. Quantitative content of the high-temperature phases in layers of the ablated nanoparticles increases with raising the intensity. The obtained nanoparticles exhibit good thermal stability.
