“…R 1+ and R 2+ ions are consumed for the formation of AlO 4 tetrahedra and decrease the NBOs. Al 2 O 3 can act as a glass modifier also, depending on its local environment and amount within glass network 16 17 . By considering the contribution of all the components of the present samples, the NBOs and BOs are calculated.…”

Agricultural waste ashes are used as resource materials to synthesize new glass and glass-ceramics. The as-prepared materials are characterized using various techniques for their structural and dielectric properties to check their suitability in microelectronic applications. Sugarcane leaves ash exhibits higher content of alkali metal oxides than rice husk ash, which reduces the melting point of the components due to eutectic reactions. The addition of sugarcane leaves ash in rice husk ash promotes the glass formation. Additionally, it prevents the cristobalite phase formation. These materials are inherently porous, which is responsible for low dielectric permittivity i.e. 9 to 40. The presence of less ordered augite phase enhances the dielectric permittivity as compared to cristobalite and tridymite phases. The present glass-ceramics exhibit lower losses than similar materials synthesized using conventional minerals. The dielectric permittivity is independent to a wide range of temperature and frequency. The glass-ceramics developed with adequately devitrified phases can be used in microelectronic devices and other dielectric applications.

“…Barium aluminotitanate glasses are of interest due to physical properties that lend them to potential applications, for example, in the encapsulation of radionucleides in highly active nuclear waste [1][2][3][4], high refractive index materials for use in high-capacity optical disk storage systems [5], broadband photoluminescent materials [6], and as precursors for glass-ceramics for optical [7] and ferroelectric [8] applications. Further applications may arise from the ability to control the local nucleation and growth of crystals to form patterned glass ceramics by systematic annealing of the glass through, for example, laser treatment.…”

Ba 0.09 Al 0.18 Ti 0.12 O 0.61 glasses have been produced by aerodynamic levitation and laser heating. Neutron diffraction, x-ray diffraction, x-ray absorption spectroscopy, molecular dynamics simulation, and reverse Monte Carlo refinement methods have been used to obtain a detailed atomistic structural model of the glass. This model has been used to investigate its atomic coordination and network structure. It is found that the Al atoms are almost exclusively fourfold tetrahedrally coordinated to oxygen atoms. In contrast, the Ti atoms coordinate to oxygen atoms in approximately equal numbers of four-and fivefold coordinated sites with a small number of sixfold sites. The results show the presence of some tetrahedral TiO 4 structural motifs although the dominant O-Ti-O bond angle occurs at 90• . It is found that Al/Ti-O network structure shows strong similarities with other oxide glass forming systems although a first sharp diffraction peak is not observed. The results are used to discuss the unusual properties of the Ba-Al-Ti-O glasses produced under different quenching conditions.

“…Apart from this, the high dielectric characteristics of Ba in barium titanate (BaTiO 3 ) makes it a primary material for electro-optic devices 28 and glass-ceramic capacitors. 29 Thus, the interesting physical properties of barium-doped glasses make them a potential candidate for nuclear applications, such as the incorporation of radionuclides of highly radioactive nuclear waste, [30][31][32][33] optical disk storage devices, 34 and glass-ceramics for ferroelectrical 35 and optical applications. 36 A selective amount of barium in glass-ceramics facilitates controlled nucleation and crystal growth to form patterned glass ceramics, 24,37,38 which are used for laser-treatment purposes.…”
