Comparative qualitative analysis of hot pressing of zirconium dioxide nanopowders

The presented study confirms that the reduction of the level of structural dimensions to the submicron and nanometric ranges is the dominant trend in the development of structural and instrumental ceramics. Following this trend with the use of traditional methods leads to an increase in cost and a significant growth of grains, which requires the introduction of additional preliminary operations, such as grinding of grains and selection of starting powders. At the same time, the application of the method of electroconsolidation under pressure in a vacuum promotes the acceleration of compaction processes, which makes it possible to overcome the shortcomings of traditional approaches when obtaining fine-dispersed, high-density ceramic structures.
