“…Recently, an enormous amount of research has been done on the impact of the glass composition on the crystallization, microstructure, and characteristics of the MAS-based glass-ceramic materials. [6][7][8] Kang investigated the impact of TiO 2 addition on the characteristics of MAS systems. Results indicated that a small amount of TiO 2 sped up the densification and enhanced the characteristics of the MAS samples.…”

In this paper, we investigated the impacts of varying CeO2 contents and heat‐treatment procedures on the crystallization, and microstructure, and dielectric characteristics of MgO‐Al2O3‐SiO2‐TiO2‐CeO2 (MASTC) materials. The research indicated that perrierite, and rutile, and α‐cordierite were the major crystalline phases in the materials. An increased CeO2 content promoted the formation of perrierite and inhibited the precipitation of α‐cordierite and rutile in the glass‐ceramics. An appropriate amount of CeO2 content contributed to a dense microstructure and improved the dielectric characteristics of the samples. However, an excessive amount of CeO2 deteriorated the densification and dielectric characteristics of the MASTC materials. Furthermore, heat‐treatment temperature and duration also had a significant impacts on the crystallization, microstructure, and dielectric performance of the materials. The MASTC material with 20.2 wt% CeO2, heat‐treated at 1100 oC for a duration of 3 h possessed superior characteristics with a density of 3.14 g/cm3, a permittivity of 11.1, and a Q×f factor of 17357 (14 GHz).This article is protected by copyright.

“…1,2 Since glass-ceramics enable controllable microstructures from a large variety of glass compositions, they have wide application in areas such as microelectronics, biomedicine, mechanical engineering, etc. 3,4 Many studies have been carried out on the glass systems for developing more suitable glass-ceramics to improve their performance. Among various glass systems, MgO-Al 2 O 3 -SiO 2 (MAS) glass-ceramics containing a Mg-Al spinel (MgAl 2 O 4 ) crystalline phase are thought to provide many excellent properties, including good chemical durability, 5,6 thermal stability, 7,8 high mechanical strength, [9][10][11] high strain point temperature, high surface smoothness 12 and good transparency in the visible range, 13,14 which makes MAS glass-ceramics potential candidates for flat panel displays and photovoltaic substrates.…”

The influences of adding ZnO and the use of specific heat-treatment schedules on MgO-Al 2 O 3 -SiO 2 (MAS) glass-ceramic properties including crystallization, micromorphology, optical transmittance and Vickers-hardness were investigated. The XRD analysis proved that MgAl 2 O 4 and Al 2 ZnO 4 spinel are the major crystalline phases formed in the studied MgO-Al 2 O 3 -SiO 2 -ZnO (MASZ) glass ceramics. The addition of ZnO facilitated the crystallization of the MAS glass and resulted in a uniform and compact microstructure. The homogeneous distribution of microcrystals with average grain size less than 100 nm in the MASZ glass-ceramics contributed to the improvement of the corresponding transmittance in the visible range. In addition, the orthogonal heat-treatment experiment indicated that the crystallization time and nucleation time have a dominant effect on the microhardness of glass-ceramics, followed by decreasing effects of crystallization temperature and nucleation temperature.
