What is the role of alumina in glass ceramics composition?4 answersAlumina plays a crucial role in glass ceramics composition. It contributes to the precipitation and transition of certain crystalline phases, such as β-quartz solid solution and lithium disilicate, resulting in the formation of glass-ceramic materials with improved properties. The addition of alumina also enhances the glass-forming tendency of the composition, leading to an increased glass-forming region.

The presence of alumina in the composition also influences the electrical properties of the glass-ceramic materials, such as dielectric constant and dielectric loss tangent. Overall, alumina plays a crucial role in the structure, properties, and performance of glass ceramics.
How can the structural modification of alumina spheres influence the growth of carbon nanotubes?3 answersThe structural modification of alumina spheres can greatly influence the growth of carbon nanotubes. The arrangement and growth of multi-walled carbon nanotubes (MWCNTs) on alumina microparticles depend on their geometry, size, and crystallography. The growth of CNTs occurs at the crystal step sites on the surface of the alumina microparticles, and the organization of the CNTs varies with the orientation of the crystal steps. Additionally, the use of alumina as a milling agent in ball-milling processes can result in the effective shortening of nanotubes, but it may also lead to amorphization and the destruction of crystallinity. These findings highlight the importance of the structural characteristics of alumina spheres in controlling the growth and properties of carbon nanotubes.
What is the effect of calcination on the structure of SiO2 and Al2O3?5 answersCalcination has different effects on the structure of SiO2 and Al2O3. For SiO2, calcination at temperatures above 1000 °C leads to the appearance of the mullite phase and an increase in crystallization activation energy. On the other hand, for Al2O3, the addition of Al2O3 content in CaO-SiO2-based mold flux melts initially reduces complex structural units but then increases them with further addition. The specific surface area and pore size of silica/alumina xerogels reach their maximum at 500-700°C, after which the samples become sintered and lose mesoporosity. In the case of SiO2 and Al2O3 composite materials, calcination temperature affects the structure and properties. Calcination at 300 °C leads to aggregation and incomplete formation of the crystalline phase, while calcination at 500 °C results in good particle separation and a well-dispersed single anatase phase.

How does aluminium doping affect the dielectric properties of tin oxide thin films?2 answersAluminium doping has a significant impact on the dielectric properties of tin oxide thin films. The addition of aluminium leads to variations in the band gap and optical characteristics of the films. It has been observed that as the aluminium concentration increases, the size of the crystallites in the films decreases, and the optical band gap decreases as well. Furthermore, aluminium doping affects the insulating characteristics and dielectric properties of the films, with lower leakage current and improved dielectric tunability and loss observed in certain aluminium-doped thin films. However, it should be noted that the quality of the films may decrease with higher aluminium doping, affecting the short-range order and resulting in changes in photoluminescence and resistivity. Overall, aluminium doping plays a crucial role in modifying the dielectric properties of tin oxide thin films.
