In this study, fine Y 2 O 3 -MgO composite nanopowders were synthesized via the sol-gel method. Dense Y 2 O 3 -MgO composite ceramics were fabricated by presintering the green body in air at different temperatures for 1 h and then subjecting the sintered bodies to hot isostatic pressing at 1300°C for 1 h. The effects of pre-sintering temperature on the microstructural, mechanical, and optical properties of the resulting ceramics were studied. The average grain size of the ceramics was increased, whereas their hardness and fracture toughness were decreased with increasing pre-sintering temperature. A maximum fracture toughness of 1.42 MPa•m 1/2 and Vickers hardness of 10.4 GPa were obtained. The average flexural strength of the ceramics was 411 MPa at room temperature and reached 361 MPa at 600°C. A transmittance of 84% in the 3-5 µm region was obtained when the composite ceramics were sintered at 1400°C. Moreover, a transmittance of 76% in the 3-5 µm region was obtained at 500°C.

by many emerging applications such as curved or bendable IR sensors. [3] When mechanical flexibility is required, polymers, such as polyethylene terephthalate and polyethylene naphthalate, are used in the visible region, but cannot be extended to the IR as they have several vibrational absorption fingerprints. There exist polymers, including parylene C, polydimethylsiloxane, polyimide, that are more transparent in the IR and have been studied in literature. [4] However, ultraviolet lithography is not always easy on such materials due to their sensitivity to chemicals. In addition, high-resolution electron beam lithography on these polymeric substrates is restricted by their limited thermal and radiation tolerance and nonplanar nature. Alternative methods like nano-stencil lithography and self assembly techniques could be employed to fabricate sub-micrometer features on these polymer substrates. [4] Besides the difficulty of finding an appropriate lithography method for patterning, the transmission spectra of these IR polymer substrates show still many vibrational fingerprints between 2 and 10 µm, which prevent their use both in most of the the near-IR (1-5 µm) and mid-IR (5-25 µm) regions.Yttria-stabilized zirconia (YSZ) is a ceramic that has received a lot of attention due to its exceptional properties such as high hardness, high dielectric constant, chemical inertness, and high ionic conductivity at elevated temperatures. [5] In the powder form it is used to make coatings that are chemically inert and tolerant to mechanical wear and tear; for example, in cutting tools, chemical tank linings, and dental restorations. [6,7] It is also used as an electrolyte in solid oxide fuel cells. [8] Lately, there is a growing interest in using thin films and microspheres of YSZ for various photonic applications. [9][10][11][12][13] ENrG Inc. has commercialized 20 and 40 µm thick flexible substrates of 3 mol% yttria (Y 2 O 3 )-stabilized tetragonal zirconia (3YSZ) ceramic, which has also shown remarkable transparency in the near-IR and mid-IR while being translucent in the visible. [14,15] In this article, we propose and demonstrate for the first time that 3YSZ can be an ideal platform to implement next generation flexible IR nano-optic devices, such as plasmonic sensors and polarizers. We also show that it can be combined with graphene to make flexible transparent electrodes for the IR that can be used for cell culture spectroscopy and IR transparent shielding. [16,17] Infrared (IR) technologies have become increasingly relevant as they offer a wide range of applications, from thermal imaging to chemical and biological vibrational spectroscopy. Substrate materials, such as calcium fluoride and zinc selenide, are commonly used for IR optics. Unfortunately, they are typically fragile or hygroscopic, thus potentially producing problems during device fabrication and in the long-term functional operation. Here, yttria-stabilized zirconia (YSZ) ceramic is introduced as a flexible and stable platform for IR nano-optics. In particul...

“…Since the properties of polycrystalline ceramics are controlled by the microstructure, it is important to control the grain growth while maintaining high density. However, highly dense ceramics with micro-or nanometer grain size are difficult to achieve with conventional sintering [30].Processes such as reducing the concentration of sintering additives such as alumina [22], pressure-assisted sintering [32][33][34][35] and spark plasma sintering [36-40] could be alternative ways to prepare dense Y-TZP ceramics with fine grain size. Changing the concentration of sintering additives may have effects on other properties such as aging resistance [21,41], and pressure-assisted sintering and spark plasma sintering may not be cost-effective since the processes are more complex, expensive, and difficult to apply [30].…”

Two-Step Sintering of Partially Stabilized Zirconia for Applications in Ceramic Crowns

et al. 2020

Partially-stabilized zirconia is used in ceramic crowns due to its excellent mechanical properties and bio-inertness but does not match the natural color and translucency of tooth enamel. To reduce scattering of light and improve translucency, the grain size of zirconia ceramics should be less than the wavelength of visible light (0.4-0.7 µm), and porosity should be eliminated. The aim of the present work was to study the effect of two-step sintering of a commercial powder (Zpex Smile, Tosoh Corp., Tokyo, Japan) on the grain size and translucency of zirconia for use in ceramic crowns. Samples were sintered at a first step temperature (T 1 ) of 1300, 1375 and 1400 • C for 5 min, followed by a decrease to the second step temperature (T 2 ) and holding at T 2 for 5-20 h. Samples were also conventionally sintered at 1450 • C for 2 h for comparison. Two-step sintered samples with an almost equal density, smaller grain size and narrower grain size distribution compared to conventionally sintered samples could be sintered. However, the translucency of two-step sintered samples had lower values compared to conventionally sintered samples. This is due to the slightly higher porosity in the two-step sintered samples. Density and translucency of both conventionally and two-step sintered samples could be increased further by using a ball milled powder.Materials 2020, 13, 1857 2 of 20 non-cubic unit cell [10][11][12][13][14][15][16]. To prepare ceramics with high translucency, it is necessary to sinter to high density (>99.9% theoretical density), avoid the presence of secondary phases (particularly at the grain boundaries) and, in the case of an optically anisotropic material such as Y-TZP, to keep the grain size small with respect to the wavelength of visible light [12,13,[15][16][17]. Porosity is considered to be the main cause of scattering [10,11,13], but as pore size is related to grain size [11,18], a reduction in grain size is still expected to be helpful in reducing scattering. The translucency of Y-TZP ceramics can also be improved by lowering the amount of alumina additive (added to increase resistance to low temperature degradation [19][20][21]) and by preparing tetragonal/cubic zirconia composite materials [17,[22][23][24][25]. However, reducing alumina content and increasing the amount of cubic zirconia phase will reduce the low temperature degradation resistance and toughness of zirconia [21,24,26]. Hence, optimizing sintering parameters in order to obtain samples with high density and fine grain size is a topic of interest.The fabrication of Y-TZP ceramics is usually carried out using solid-state sintering at a high temperature (1350-1550 • C) [26][27][28]. The high sintering temperature promotes not only densification but also grain growth [29][30][31] and the formation of the cubic phase of zirconia [26,27]. Since the properties of polycrystalline ceramics are controlled by the microstructure, it is important to control the grain growth while maintaining high density. However, highly dense ceramics with micr...
