Summary

Yttrium titanium oxide was synthesized, using a sol-gel process, to act as a sintering aid. The process formed a titanate with the calcium fluorite crystal structure. This phase is known to be present at high temperatures yet remained stable at room temperature. Various heat treatments were performed to determine the stability of the resultant phase. Simultaneous Thermal Analysis was used to determine the reaction events and stability of the reactions of the precursor and the crystalline titanate powder. X-ray diffraction and Reitveld refinement were performed to evaluate the resultant phases.
