Pressure-assisted densification was used by way of a hot press to optimize the conditions of heat and pressure when applied to anatase (TiO2). This study optimized hot-pressing conditions, which will be helpful when doping TiO2 because it will allow optimization of bulk anatase for transparent conductive oxide (TCO) applications. Lessons learned can also guide thin-film deposition strategies. X-ray diffraction was used to determine the grain size, micrographs were used to determine the density, and a D-Optimal design (using computer software known as “Design Expert”) optimized tests and determined the best heat and pressure parameters. It was found that 700 ºC and 700 MPa yielded the highest density while maintaining nanoscale grain size.
