Zirconium Dioxide Fibers and Methods of Obtaining Them

Abstract

New designs of high-energy machine building units require materials with improved performance properties, especially for operating in high-temperature conditions. Heat-shielding materials based on refractory oxides have a number of advantages due to extremely low values of thermal conductivity and bulk density and high operating temperatures. At the current stage of technological development in the world, mass production and application of heat-shielding materials based on alumina and silica fibers have been mastered. Zirconium dioxide fibers with high refractory properties are used to create heat-shielding and heat-insulating materials for operating temperatures above 1600 °C. In this paper, an attempt was made to obtain zirconium dioxide fibers in two ways – by the sol-gel method and by electrospinning, to produce heat-insulating materials for high-temperature applications.
