The size of the particle ranges from 10 to 80 nm, and the largest one can even reach 200 nm, which may begin to grow in the initial stage of the reflux. Transmission electron microscopy and high-resolution electron microscopy (HREM) were used to characterize the microstructure of these nanoparticles. Using silicon single crystals as internal standards, the polycrystalline diffraction pattern analysis shows only presence of cubic Sb2O3 phase. The bright-field micrograph displays chat the particles may have various polyhedral configurations. HREM results show that the particles are crystallographically perfect. Moreover, the formation mechanism of nanoparticles is discussed 关键词: antimony compounds;nanostructured materials;particle size;powder technology;transmission electron microscopy;oxide nanoparticles;polyvinyl alcohol;particle size;transmission electron microscopy;high-resolution electron microscopy;HREM;microstructure;TEM;polyhedral configurations;nanoparticle formation mechanism;powder technology;Sb2O3
