Porous titania beads serves as an ideal packing material for chromatography [1].The popularity is attributed to their excellent chemical/mechanical stability over silica and organic polymeric material
Various technologies for preparing micron-sized particles have been developed and are currently used in many processes (e.g.milling,grinding,crushing,spray drying and recrystallization from liquid sol
