- Abstract
Differential thermal and x-ray-phase analysis methods are used to study properties of ZrO2 powder stabilized with yttrium oxide, prepared by sol-gel technology using an organo-mineral solution. Optimization of powder preparation, including firing and deagglomeration treatment, makes it possible to prepare dense ceramic with a sintering temperature of 1350°C with an average grain size of 250 – 290 nm. Deagglomerated powder may be used as an addition in the preparation of high quality refractories based on oxide raw material.
