煅烧制度对Lu2Ti2O7粉体生长形貌的影响
Influences of Calcining Process on Lu2Ti2O7 Powder Morphology
摘要
Abstract
Lu2Ti2O7 powders were prepared by molten salt synthesis process. The effect of calcining process on morphology of Lu2Ti2O7 powder was investigated. The efficient processes were determined. Lu2Ti2O7 powders were characterized by XRD and SEM. Based on these experimental results, a preliminary growth mechanism of time-dependent particle evolution was given. The studies revealed the nucleation and growth rate played important roles in determining the geometric shape and size of the product. High nucleation and particle growth rate easily made the agglomerated crystals convert into hexahedral prismatic form while the smaller nucleation and growth rate allowed the particles to have good crystallinity and regular polyhedral crystal faces.关键词
