Development of modern engineering materials is a task of long-term relevance. Technological advancements lead to new developments in materials engineering. This paper examines modern high-density materials on the basis of zirconium dioxide with varying concentrations of yttrium oxide, which is a stabilizing agent that influences the phase composition of material and the end properties of products. It was verified that the developed ceramic materials can withstand drastic changes in temperature varying from +20 to +700 °С avoiding fracture and at the same time retain stable phase composition during operation. The studied materials find application as a ceramic carrier base in oxygen partial-pressure sensors designed for different gas media. The ceramic base was produced by casting of ceramic tapes over the moving maylar substrate. This technique enables to produce tapes with thicknesses from 150 to 400 μm. This research looked at specimens with the thicknesses of 250–270 μm. The paper describes the results of a laboratory study that analysed the ability of ceramic carrier base to withstand fracture when being heat up to 650–700 °С and then shock cooled to room temperature. The results of X-ray diffraction and structural analyses before and after the tests are also described. Apparent volume weight and open porosity of the specimens have been determined. A laboratory testing technique has been developed that simulates the actual environment in which oxygen partial-pressure sensors operate and can validate the instruments’ operability. The authors established the nature of cracking that occurs in the material under repeated temperature cycling (from +25 to +700 °С). They also found a relationship between metastable phases and the production of ceramic tapes with stable properties (such as average density, open porosity, relative density, phase composition).

This research was funded by D. Mendeleev University of Chemical Technology of Russia. Project No. 041-2018.
