ジグリコール添加した ZrOCl₂ 溶液から合成したナノ ZrO₂ 粒子のキネティックス研究

抄録

Monodispersed yttria stabilized ZrO₂ nanocrystals were synthesized from zirconium oxyhydrate sols chelated with diglycol. The particle growth kinetics as a function of the concentration of ZrOCl₂ solution and molar ratio of ZrOCl₂: diglycol was investigated. It was demonstrated that the rate constant of the particle growth and the final particle size increased with increasing the concentration of ZrOCl₂ solution and decreasing the molar ratio of ZrOCl₂: diglycol. High-resolution transmission electron microscopy (HRTEM) as well as powder X-ray diffraction showed that the as-synthesized nanoparticles were well crystalline.
