A novel, simple and inexpensive quasi-gaseous state reaction method for synthesizing ZrO2 spheres has been developed in our recent work. SEM characterization shows that fairly spherical ZrO2 particles with smooth surface and average diameter of 1.71 μm with the standard deviation of 0.49 μm, have been obtained by using the new process. The spheres prepared have three types of structure: the homogeneous and dense structure, the structure with a loose core and dense shell, and the hollow structure. XRD measurement demonstrates that the phase composition of ZrO2 spheres after calcining at 600 ℃ is major c-ZrO2.
