Microstructural Evolution of Single-Grain-like TiO2 Microspheres Prepared Through Spray Drying and Multi-Step Sintering

The preparation of TiO2 microspheres by spray drying followed by controlled sintering was investigated. Starting from commercial rutile TiO2 nanoparticles dispersed in water, spherical microspheres with broad size distributions were produced by adjusting key spray-drying paramete...
