高温固相法制备的样品普遍存在形貌不规则且易团聚现象，单纯从SEM图中分

Prepared by high temperature solid phase method irregular morphology sample ubiquitous and easy agglomeration, derived from the simple analysis of the SEM images Li introduced sample size is increased to enhance the crystallinity and inaccurate, consider adding an appropriate flux samples improved morphology and particle size distribution. Please add on.

Samples prepared by high temperature solidphase method are generally irregular and easy to reunite, and simply from the analysis of the SEM diagram, Li introduced increased the granularity and enhanced crystallization is not accurate, and consideration can be given to adding suitable fluxes to improve the appearance and granularity distribution of the sample. Please add.

Samples prepared by high temperature solid phase method generally have irregular morphology and are easy to agglomerate. It is concluded from the analysis of SEM that the introduction of Li increases the particle size and crystallinity of samples, and appropriate flux can be added to improve the morphology and particle size distribution of samples.
