Three different feedstock powders with increasing SiO2 content were used in experiments. Resulting materials were characterized by a variety of analytical and microscopy techniques and selected mechanical properties were measured as well. The as-sprayed materials were amorphous or partially nanocrystalline depending on their SiO2 content. The as-sprayed material has low porosity and crystallizes when heated to approximately 950ºC. By controlled annealing to crystallization temperature, nanocomposite structures were produced with predominant tetragonal-ZrO2 nanocrystallites embedded in amorphous matrix. With increasing SiO2 content, the crystallization rate decreased and the average crystallite size increased.
