摘要：
Zirconia particles, methods of making zirconia particles, composite materials that contain the zirconia particles, methods of making the composite materials, and zirconia sols that contain the zirconia particles are described. The zirconia particles are substantially non-associated and have an average size no greater than 50 nanometers and may contain yttrium. The zirconia particles are prepared by a method that includes two separate hydrothermal treatments.
