Preparation method of anti-sintering YTaO4 spherical spraying powder
The invention relates to a preparation method of anti-sintering YTaO4 spherical spraying powder, the preparation method comprises the following steps: conveying YTaO4 particle powder in a certain particle size range to a plasma flame area in a high-temperature plasma reactor through carrier gas, heating and melting at high temperature, and condensing to obtain a YTaO4 sphere. Due to high-temperature treatment, the sintering resistance of the material is excellent. According to the method, the YTaO4 spherical powder with good sintering resistance, high spheroidization rate and good fluidity can be obtained, the implementation method is simple and easy to implement, the performance is more excellent, and the method can be applied to the fields of thermal spraying and the like and is suitable for industrial large-scale production of the YTaO4 spherical powder.
本发明涉及一种抗烧结YTaO4球形喷涂粉的制备方法，将一定粒径范围的YTaO4颗粒粉通过载气输送到高温等离子体反应器中的等离子火焰区域，高温加热熔化，在冷凝后即得球形YTaO4球形。由于经过超过高温处理，材料的抗烧结性极佳。该法可以得到抗烧结性好、球化率高、流动性好的YTaO4球形粉末，实现方法简单易行，性能更优异，可应用于热喷涂等领域,适用于工业化大规模生产YTaO4球形粉末。
