Long-term leaching kinetics and solution chemistry of aqueous BaTiO powder suspensions: a numerical model supported experiment.

The advent of lead-free perovskite materials with favorable toxicity profiles has made them candidates for and environmental applications. However, their tendency to leach A-site cations raises concerns about toxicity, catalytic efficiency, and slurry properties. The present study investigates the long-term leaching kinetics of BaTiO powders over 31 days in aqueous solutions of varying pH levels.
