Abstract:

The fabrication technology of powders of the ZrO2-Y2O3 composition with rod-shaped particles by the saturation of viscose fabric with zirconyl and yttrium nitrate solutions followed by drying, annealing at 1400A degrees C, and screening is proposed. The influence of production parameters (the concentration of zirconyl nitrate in the starting solution, saturation time and temperature, and drying temperature) on geometric parameters (height and diameter) of powder particles is investigated. It is established that the diameter of the viscose fiber and the concentration of the starting solution affect the size of the particles that form most substantially. The particle height is determined by the cell size of the sieve on which the roasted viscose fabric is sieved and by the number of trituratings. It was established that the fluidity of powders substantially increases as a result of multiple trituratings through a sieve with a cell size of 315 mu m and with an increase in the concentration of saturating solutions. Preparing 1 kg of the ZrO2-7\% Y2O3 powder under optimal conditions requires about 10 m(2) of viscose fabric.
