“…1 and the results presented in Fig. 2, the strong tendency of these cordierite phases to nucleate at the surface14041 and the composition of the initial glass, the most logical explanation for these observations is that indialite was the last phase to crystallize. It probably grew along connected channels of residual glass formed by the growth of the YS-phases and thus filled large surface areas which do not appear to be connected at the immediate surface.…”

“…By contrast, a systematic orientation change has been observed in indialite crystals grown in a boron doped MgO/Al 2 O 3 /SiO 2 (MAS) glass41. Comparably small orientation changes and a topography were observed in indialite containing domains after crystallization in a related MAS system free of Y 2 O 3 1. It seems to be typical for indialite to vary its crystal orientation when faced with growth obstacles, i.e.…”

“…In the past few years, glasses and glass-ceramics of the system MgO/Al 2 O 3 /SiO 2 have gained a great deal of interest, mainly due to their good mechanical properties such as high hardness, high Young’s moduli, high strength and a high fracture toughness12345 as well as to their interesting dielectric properties678. These glass-ceramics have frequently been proposed for various applications such as hard disc substrates9, millimeter-wave dielectrics67 and dental materials3.…”

The crystallization behavior of a glass with the composition 54.7 SiO2·10.9 Al2O3·15.0 MgO·3.4 ZrO2·16.0 Y2O3 is studied using X-ray diffraction (XRD), scanning electron microscopy (SEM) including electron backscatter diffraction (EBSD) and (scanning) transmission electron microscopy [(S)TEM] including energy-dispersive X-ray spectrometry (EDXS). This glass shows the sole surface crystallization of four different yttrium silicates of the composition Y2Si2O7 (YS). The almost simultaneous but independent nucleation of α-, β-, δ-, and ε-YS at the surface is followed by growth into the bulk, where ε-YS quickly dominates a first crystallized layer. An accumulation of Mg at the growth front probably triggers a secondary nucleation of β-YS, which forms a thin compact layer before fragmenting into a highly oriented layer of fine grained crystals occupying the remaining bulk. The residual glass between the YS growth structures allows the crystallization of indialite, yttrium stabilized ZrO2 (Y-ZrO2) and very probably μ-cordierite during cooling. Hence, this glass basically shows the inverted order of crystallization observed in other magnesium yttrium alumosilicate glasses containing less Y2O3. An epitaxial relationship between Y-ZrO2 and ε-YS is proven and multiple twinning relationships occur in the YS phases.

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.
