Abstract
Use synthesis of calcium carbonate particles, and their use as templates for further modification, with the aim of their use as abrasives in toothpaste formulations, is explored in this dissertation. Linear polyols were shown to have a strong affect on the morphology of precipitated calcium carbonate particles, as well as a stabilizing effect of the vaterite polymorph. Calcium carbonate particles were successfully coated with silica via a condensation reaction, as well as in polymer via a seeded dispersion polymerization. Calcium carbonate particles were used as sacrificial templates to produce calcium fluoride particles with the same morphology as the template. Synthesised particles were shown to have tooth cleaning abilities similar to commercially used abrasive particles, but significant conclusions regarding how their morphology affected this could not be drawn due to unreliable data.
