Abstract
Transparent lithium aluminum silicon glass‐ceramics are prepared via heat treatment and the effect of boron oxide (B2O3) content on the structure and properties of Li2O‐Al2O3‐SiO2 glass‐ceramics is investigated. The X‐ray photoelectron spectroscopy results reveal that the parent glass containing B2O3 exhibits a higher concentration of bridging oxygen (BO). With an increase in B2O3 content, the relative amount of BO changes from 76.64% to 79.86% and then to 79.52%. Simultaneously, the second crystallization peak temperature TP2 of the samples increases from 715°C to 720°C and then to 724°C by differential scanning calorimeter analysis. The X‐ray diffractometer and scanning electron microscope results indicate that the addition of B2O3 facilitates grain growth, while an increase in B2O3 substitution for Al2O3 hinders the precipitation of LiAlSi4O10 but promotes quartz formation. The glass containing 2 wt% B2O3 with the heat treatment of 560°C/ 4 h+ 680°C/2 h shows a Vickers Hardness value of approximately 7.75 GPa, and a transmittance at 550 nm reaching ∼85%.
期刊介绍:
The International Journal of Applied Glass Science (IJAGS) endeavors to be an indispensable source of information dealing with the application of glass science and engineering across the entire materials spectrum. Through the solicitation, editing, and publishing of cutting-edge peer-reviewed papers, IJAGS will be a highly respected and enduring chronicle of major advances in applied glass science throughout this century. It will be of critical value to the work of scientists, engineers, educators, students, and organizations involved in the research, manufacture and utilization of the material glass. Guided by an International Advisory Board, IJAGS will focus on topical issue themes that broadly encompass the advanced description, application, modeling, manufacture, and experimental investigation of glass.
