“…The changing trend of the relative density is consistent with the phenomena shown in Figure 4. The hardness of ceramics is mainly affected by the relative density and grain size 32–35 . When the grain size of the ceramics is similar, the relative density is the main reason for affecting the hardness.…”

Effects of treatment modes of precipitates in the coprecipitation method on the resulting YAG nanopowders and ceramics are investigated. Three treatment modes for precipitates, namely, single water washing, water–ethanol washing, and water washing–ethanol immersion, are conducted to prepare the YAG nanopowders. The average particle size (∼62 nm) and distribution (mainly ranging from 30 to 110 nm) of the powders obtained by the three modes are similar. However, the dispersity of the three powders shows large differences. The nanopowder obtained via water washing–ethanol immersion possesses optimal dispersity without any agglomeration, whereas that obtained via single water washing comprises substantially hard agglomerations. The relative density, Vickers hardness, and optical in‐line transmittance of the ceramics prepared via water washing–ethanol immersion, respectively, reach 99.85%, 14.1 ± .4 GPa, and 77.8% at 1064‐nm wavelengths after spark plasma sintering. These results are markedly superior to those of the ceramics prepared using the two other modes (97.43%, 6.8 ± .7 GPa, and 17.2% at 1064‐nm wavelengths and 98.97%, 10.2 ± .5 GPa, and 47.8% at 1064‐nm wavelengths, correspondingly). Therefore, water washing–ethanol immersion is a sensible and advisable treatment mode of precipitates for preparing YAG nanopowder and ceramics via coprecipitation.

“…[ 5 ] Compared with these transparent materials, yttrium aluminum garnet (Y 3 Al 5 O 12 ) transparent ceramics enjoy the advantages of a higher quality factor and permittivity, in addition with the characteristics of low density, high hardness, corrosion resistance, high strength, transparency from near‐ultraviolet to mid‐infrared range, and high temperature stability. [ 19–22 ] Hence, the Y 3 Al 5 O 12 transparent ceramics can be an excellent candidate to be applied to a decorative antenna or other multifunctional antennas.…”

The Y3Al5O12 transparent dielectric ceramic is of permittivity εr ≈10.53 and Q × f ≈ 95219 GHz (Q = quality factor = 1/tanδ and f = 7.37 GHz), which is excellent to be applied for the dielectric resonator antenna (DRA). A dual‐band filtering DRA (FDRA) is proposed to verify the special dielectric properties of Y3Al5O12 transparent dielectric ceramic. The FDRA is designed by seamlessly integrating a dual‐band DRA based on rectangular Y3Al5O12 transparent ceramic with a quadruple‐mode stub‐loaded loop resonator (SLLR). The DRA operates at the TE111y and TE113y modes excited by a common coupling slot. The SLLR serves as a feeding network, whereas the DRA works as a dual‐mode resonator as well as the radiating element. The reflection coefficient, realized gain, and the radiation pattern of the dual‐band FDRA are examined. It is observed that the proposed FDRA operates at 3.42 and 5.28 GHz with impedance bandwidths of 5.8% and 4.0%, respectively, which are used for the fifth‐generation (5G) network and applications. Good dual‐band filtering performance is achieved while realizing radiation efficiency above 84.1% and 85.4% at two bands.
