高温固相法制作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

High temperature solid phase method produced a sample ubiquitous irregular morphology 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 produced by high temperature solidphase method are commonly irregular and easy to reunite, and simply from the analysis of 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.

The sample prepared by high temperature solid-state method has irregular morphology and easy agglomeration. It is concluded from the analysis of SEM that the introduction of Li increases the particle size and crystallinity of the sample inaccurately. It can be considered to add appropriate flux to improve the morphology and particle size distribution of the sample. Please add.<br>
