The dataset contains the files and raw data for a submitted manuscript named: Long-term leaching kinetics and solution chemistry of aqueous BaTiO3 powder suspensions: A numerical model supported experiment. The purpose of the dataset is to allow other researchers to replicate the study and model output.

The data has been generated from the exposure of BaTiO3 powders made in-house to aqueous HCl solutions of different pH for varying periods of time up to 31 days. The data gives a comprehensive description of the dissolution/leaching behavior of the perovskite BaTiO3 in aqueous environments. The dataset contains data from: Inductively coupled plasma mass spectrometry (ICP-MS) from the liquid solution after centrifugating out the BaTiO3 powders upon completion of an individual experiment. pH data obtained over the course of each individual liquid exposure experiment. Scanning Electron Microscopy (SEM) micrographs of BaTiO3 powders before, and after exposure to the different solutions. X-Ray Diffraction (XRD) diffractograms of BaTiO3 powders before, and after exposure to the different solutions. Energy Dispersive X-ray Spectrometry (EDXS) analysis of BaTiO3 powder after exposure to aqueous solution. Particle Size Distribution (PSD) analysis of BaTiO3 powder before exposure to liquid. Brunauer-Emmett-Teller (BET) analysis of BaTiO3 powder before exposure to liquid. Plain text model output data from a numerical model of the chemical kinetics of the system in the proprietary software COMSOL Multiphysics. The model files are also included.
