Nanostructured composite particles of nano- and submicron sizes were synthesized by a combination of sol–gel and sonochemical techniques. Their graphene content was 0.8–0.9 wt%. These layered particles consisted of graphene sheets in which zirconia nanocrystals were discretely incorporated. The synthesized powders were characterized using XRD, TEM, HRTEM, diffusion aerosol spectrometry and elemental analysis. A comparison of the compressibility modulus, limit values of linear section deformation and compressibility factor shows that the compressibility of the composite is difficult to achieve compared to that of pure zirconia, apparently, due to the low elasticity of graphene sheets.

石墨烯-氧化锆复合纳米结构粉末的相组成、形貌和可压缩性
通过溶胶-凝胶和声化学技术的结合，合成了纳米和亚微米尺寸的纳米结构复合颗粒。它们的石墨烯含量为 0.8-0.9 wt%。这些层状颗粒由石墨烯片组成，其中不连续地掺入氧化锆纳米晶体。使用XRD、TEM、HRTEM、扩散气溶胶光谱和元素分析对合成的粉末进行表征。压缩模量、线性截面变形极限值和压缩系数的比较表明，与纯氧化锆相比，复合材料的可压缩性很难达到，这显然是由于石墨烯片的低弹性。
