Suoyi Spherical Yttrium Oxyfluoride Yof for Thermal Spray Coating Plasma Powder

Yttrium oxyfluoride represented by YOF usually has a rhombohedral crystal structure at room temperature, a cubic or tetragonal crystal structure at a temperature higher than 600 ° C., and 550 to 600 ° C. when cooled from a high temperature. It is known to exhibit a phase transition from cubic or tetragonal to rhombohedral. Since this phase transition is accompanied by a volume change, stress associated with the phase transition is generated during cooling in yttrium oxyfluoride. When yttrium oxyfluoride is heated from room temperature to a temperature higher than 600 ° C., stress due to the same phase transition is generated. For example, if yttrium oxyfluoride has a shape that is greatly affected by distortion due to volume change, such as a film or a bulk, this stress causes cracks and cracks.
