Prugressi recenti è sfide di a ceramica AlON trasparente
2023-05-10Ceramics and their composites have been widely investigated for various applications due to their unique chemical and physics properties [1−7]. Among them, transparent ceramics have an extensive application in the business domain and the military industries due to their outstanding optical, physical, and mechanical properties [8−10]. Among the transparent ceramics, transparent aluminum oxynitride (AlON) ceramics have been considered as one of the most important ceramics in the domes, infrared and visible windows, and transparent armors, etc [11−13]. Compared with the single crystal sapphire, which is well-known as the hardest transparent ceramics, the polycrystalline AlON ceramics have similar characteristics on strength, hardness, and optical properties, but offer more flexibility in size and shape [14,15]. Therefore, AlON ceramics have attracted a growing investigation. γ-AlON is a solid solution of Al2O3and AlN [16,17]. Many methods have been explored to prepare AlON powder or AlON ceramics, such as solid-state reaction [18], carbonization method for Al2O3[19,20], chemical vapor deposition [21], sol−gel method [22,23], and solution combustion synthesis [24]. The band gap of AlON was measured to be 6.2 eV [25]. TU et al [26] employed a first-principles density functional theory (DFT) to study the on-site preference of Al vacancy and Natoms in γ-AlON. The band gap and bulk modulus structural model of γ-AlON, as the local structure of the Al23O27N5were calculated to be 3.99 eV of N atoms and Al vacancies in γ-AlON is not and 200.9 GPa, respectively. Given a wide band clear. The properties of γ-AlON are displayed in gap together with low photon energy and high Table 1 [14].
