WebJul 2, 2012 · ZnO nanoparticles were prepared by coprecipitation method at 450C. X-ray diffraction result indicates that the sample is having a crystalline wurtzite phase. Transmission electron microscopy (TEM) result reveals that the ZnO sample is spherical in shape with an average grain size of about 50nm. X-ray peak broadening analysis was … WebCrystallographic calculator This page was built to translate between Miller and Miller-Bravais indices, to calculate the angle between given directions and the plane on which a lattice vector is normal to for both cubic and hexagonal crystal structures.
