“…The obtained film is of high purity and has good uniformity. There are many types of films that can be synthesized using the hydrothermal and microwave hydrothermal methods, such as BaTiO 3 [106,107], SrTiO 3 [108,109], ZnO [110,111], TiO 2 [112,113], etc. Wu et al [114] reported a simplified hydrothermal method to grow high-quality ZnO thin films on (0001) sapphire substrates.…”

With the continuous development and progress of materials science, increasingly more attention has been paid to the new technology of powder synthesis and material preparation. The hydrothermal method is a promising liquid phase preparation technology that has developed rapidly during recent years. It is widely used in many fields, such as the piezoelectric, ferroelectric, ceramic powder, and oxide film fields. The hydrothermal method has resulted in many new methods during the long-term research process, such as adding other force fields to the hydrothermal condition reaction system. These force fields mainly include direct current, electric, magnetic (autoclaves composed of non-ferroelectric materials), and microwave fields. Among them, the microwave hydrothermal method, as an extension of the hydrothermal reaction, cleverly uses the microwave temperature to compensate for the lack of temperature in the hydrothermal method, allowing better practical application. This paper reviews the development of the hydrothermal and microwave hydrothermal methods, introduces their reaction mechanisms, and focuses on the practical application of the two methods.

“…Moreover, the hydrothermal method for film preparation is simple, the hydrothermal treatment temperature is low, and the films obtained are of high purity and of good homogeneity, 24 this has been reported by growing ZnO thin films by hydrothermal method and they are of high quality with smooth surface and no obvious oscillation and are available for fabrication of applicators; 25 in addition to many types of membranes that can be manufactured using this method, such as: BaTiO 3 , 26,27 SrTiO 3 , 28,29 ZnO, 30,31 TiO 2 , 32,33 MgO-SiO 2 -graphite-H 2 O; 34 in comparison with other methods due to limitations of the equipment and method of deposition, which makes it difficult to produce on a large scale. 8,24,35 In addition, some factors such as sedimentation rate and substrate temperature, environmental conditions play a role in the formation and homogeneity of thin films; also, to determining the physical and optical properties.…”

This search displays the effects of deposition temperature on the physical properties of MgO-SiO2 thin films. These thin films were deposited on glass substrates using the autoclave method (within 120 min) at a temperature deposition range of 150–300°C. These films were diagnosed using X-ray diffraction (XRD), scanning electronic microscopy (SEM), and UV–Vis spectrophotometer for structural, morphological, and optical analysis, respectively. Using energy dispersive spectroscopy(EDX), the compositional characterization analysis of the MgO-SiO2 films was also carried out.The XRD patterns reveal that the MgO-SiO2 films have a cubic and hexagonal phase polycrystalline composition with the preferential growth direction of (0 0 2) and (0 1 1) respectively. Granular size was found to decrease by increasing the deposition temperature except at 200°C. The crystal and optical parameters were calculated and are discussed in detail. Membranes were found to have an absorption coefficient below (104 Cm-1) which means indirect permissible and forbidden electronic transitions. The SEM observations show that the films have homogeneous surfaces with clear fullness. The experimental results reveal that MgO-SiO2 thin films may be used as an alternative material for environmentally friendly buffer layer.
