Formation and Application of High Reflectivity Controllable Barium Sulfate Microspheres
Crystals, 2018 This paper investigated the influence of reaction conditions on particle morphology. X-ray powder diffraction (XRD), particle size distribution (PSD), and scanning electron microscopy (SEM) were used to characterize the morphology of barium sulfate.
