As a first demonstration of the complete process and to show that carbonates could be used in this process route, a suspension of calcium carbonate was mixed with a titania (rutile) suspension in a 1:1 mol ratio and processed using the full workflow described above. Powder X-ray diffraction data obtained for a sample calcined to 1150 °C (Fig. ) for 4 hours shows that the vast majority of the material has reacted to form calcium titanate with only a very small amount of unreacted rutile and calcium carbonate formed during cooling from residual CaO. This example shows that the initial steps provide adequate mixing and accurate dispensing of quantities (Fig. ) to enable successful calcination of the mixture leading to reaction to yield the desired product. The confirmation that the reagents used react successfully is critical as our main aim here is materials discovery where the formation of phases, either known or unknown, is required.
