This article reviews promising studies on the design, manufacturing, microstructure, properties, and applications of glass‐ceramics containing ZrO2 and relevant glass‐ceramic matrix composites. After the addition of ZrO2 to a glass‐ceramic composition, it can persist in the residual glassy phase, facilitate nucleation, and/or precipitate as ZrO2 or another zirconate crystalline phase. Also, ZrO2‐reinforced or ZrO2‐toughened glass‐ceramics can be designed as composites. In this article, the term “ZrO2‐containing glass‐ceramics” encompasses all these scenarios in which ZrO2 is present. Such glass‐ceramics offer a wide range of applications in modern industries, including but not limited to architecture, optics, dentistry, medicine, and energy. Since S. Donald Stookey's discovery of glass‐ceramics in the early 1950s, the most important scientific efforts reported in the literature are reviewed. ZrO2 is commonly added to glass‐ceramics to promote nucleation. As a result, the role of ZrO2 in structural modification of residual glass and stimulating the nucleation in glass‐ceramic is first discussed. ZrO2 can also be designed into the main crystalline phase of glass‐ceramics, contributing achieving super high fracture toughness above 4 MPa·m0.5. Experimental and computational studies are reviewed in detail to elucidate how the transformation toughening and other mechanisms help to achieve such high values of fracture toughness. Sintered and glass‐ceramic matrix composites also show promise, where ZrO2 contributes to improved stability and mechanical properties. Finally, we hope this article will provoke interest in glass‐ceramic materials in both the scientific and industrial communities so that their tremendous technological potential in developing, for example, tough, thermally stable, transparent, and biologically compatible materials can be realized more widely.

The properties of the glass phase of fused refractories containing 28‒94 % ZrO2 are given. The influence of the glass phase composition on the main performance properties of refractories ― corrosion resistance and tendency to release defects is considered. It is shown that a decrease in the amount of glass phase in fused baddeleyite-corundum refractories with a simultaneous increase in the amount of ZrO2 leads to an increase in their corrosion resistance and complication of the annealing conditions of products. The properties of the glass phase, which determine the tendency of refractories to release defects, depend mainly on the SiO2 : Na2O, the purity of raw materials and the method of melting the charge. Oxidative melting with the treatment of the melt with an oxygen-gas mixture is a prerequisite for the formation of a refractory glass phase in refractories and the production of products with a low tendency to the release of defects.
