以无机物为前驱物，用内凝胶法制备了适合于等离子喷涂的、粒径在10～50μm范围内的、用氧化钇稳定的氧化锆（YSZ）球形粉末，实验结果表明，通过改变乳化条件可以控制这种粉末的形貌、粒径和粒度分布．利用SEM和光学显微镜观察发现，用该方法得到的粉末主要是球形的，并且符合粒径分布的要求（5～50μm）．致密的球形粉末显示出良好的流动性．差热分析表明，用47mol％氧化钇稳定的氧化锆（YSZ）粉末在468℃有一放热峰，是YSZ粉末的相转变温度．XRD分析表明，上述粉末在800℃条件下煅烧可以得到100％非平衡四方相（t’）的YSZ粉末，没有单斜相存在．
The YSZ spherical powders stabilized with Y2O3 were prepared by the in-gel method with the aid of the in-gel method. The experimental results showed that the YSZ spherical powders with the diameter of 10 ~ Conditions can control the morphology, particle size and particle size distribution of the powder. SEM and optical microscopy showed that the powders obtained by this method were mainly spherical and meet the requirement of particle size distribution (5 ~ 50μm). Dense spherical powder shows good fluidity. Differential thermal analysis showed that the 47 mol% yttria-stabilized zirconia (YSZ) powder had an exothermic peak at 468 ° C, which was the phase transition temperature of the YSZ powder. XRD analysis shows that the above powder can be calcined at 800 ℃ to obtain YSZ powder with 100% unbalanced tetragonal phase (t ’) without any monoclinic phase.
