Description
A recycling process was developed for barium titanate based waste material, which is produced in the large scale industrial production of ceramic capacitors and related devices. Barium titanate powder was first dissolved in a concentrated aqueous HCl solution, followed by dilution with water and heating to 100°C, which resulted in the precipitation of a white crystalline titania powder. The crystalline phase of the prepared titania can be controlled by the preparation conditions, i.e., heating rate, and this process successfully produced pure anatase powder with good photo-catalytic activity. The barium ion, another main component, was also separated as barium sulfate by a simple precipitation process.<br>
