“…4(d). This is in good agreement with XRD result that atomic arrangement of this composite was ZnAl 2 O 4 with face centered cubic arrangement [8]. These results reveal that with the optimal condition of sol-gel synthesis, zinc aluminate nanoparticles could be successfully fabricated.…”

“…In general, both alumina and zinc oxide exhibit opaque white color when they are in bulk form. Meanwhile, many emerging applications, which would prefer to employing such a composite in field emission or conductive film, require an excellent optical transparency and high specific surface area [6][7][8]. Accordingly, control of its primary size within the nanometer level is indispensable for its actual utilization.…”

“…12 Similar results published by Yue et al. 13 show the tensile strength of the developed composite material improved significantly by the addition of ZnAl 2 O 4 and ZnO coated Al borate whiskers. It is well noted that the material properties can enhance by the incorporation of rigid particles or fibers throughout the structures.…”

The study focuses on the microstructural, phase transformation, and physical and mechanical aspects of aluminum/zinc oxide composite produced by a hybrid microwave sintering technique. In the present case, zinc oxide nanorods were synthesized through a cost-effective thermal decomposition method. The obtained zinc oxide nanorods’ length was in the range of 76–168 nm observed through high-resolution transmission electron microscopy images and crystallinity nature was confirmed by the bright spot in the selected area electron diffraction pattern. Two different wt% (i.e. 0.5 and 2) of zinc oxide nanorods were utilized for the fabrication of the composite material. The diffraction pattern of the milled powder and energy dispersive spectroscopy results shows effective diffusion of zinc oxide nanorods in the aluminum. The elemental mapping of milled powder illustrates the uniform distribution of the reinforcement over matrix material. The micro-hardness results exhibit a higher hardness of 27.78% with a small fraction of 2 wt%. The nano-indentation results confirm the improvement in the nano-hardness by 32.21% with 2 wt% of zinc oxide with a marginal decrease in elastic modulus by 4.92%.

“…This technique is much simpler and cheaper than the SD method, which is appropriate for practical large-scale productions. Most researchers have focused on the preparation and optical properties of alumina-zinc oxide composite (AZO or ZnAl 2 O 4 spinel) films [21][22][23][24][25]. Few works have been reported on the bulk of these composites because the preparations of ZnO gels doping with aluminum are difficult and the obtained powders have poor optical properties [26].…”

a b s t r a c tZinc aluminate spinel cryogels with various molar ratio of Al/Zn are synthesized by sol-gel technology followed by vacuum freeze drying. The structures and optical properties are both found to be affected by the molar ratios of Al/Zn and annealed temperatures. The peaks of zinc oxide (ZnO) and zinc dialuminum oxide (ZnAl 2 O 4 ) are both obtained for the samples with more Zn content annealed at 750 • C or upward. The composites have a large surface area (137 m 2 /g) with mesoporous structure after annealing at 750 • C. The SEM images reveal that the ZnAl 2 O 4 crystals formed a multilayer structure with redundant ZnO particles which deposited on it. Furthermore, the maximum infrared reflectance is about 80% with an improvement of 35% in the infrared region after annealing at 950 • C compared with that of 450 • C, which indicates that these porous cryogels have a potential application as thermal insulating materials at a high temperature.
