Abstract

Lithium aluminosilicate glass-ceramics has many uses in high-tech applications. Beta quartz or spodumene solid solution phase in the Li2O-Al2O3-SiO2-P2O5 glass system has been precipitated by controlled heat-treatment of the parent glass. These glasses prepared by melt-quench technique. High transparency (>80%) in the visible wavelength range has been observed in the material by UV-VIS-NIR spectrometry. FTIR spectra indicated the presence of Si-O as well as Al-O bonds in the glass-ceramics. The LAS glass ceramics showed moderate flexural strength (~80 MPa) and young’s modulus (~50 GPa). Microstructural characterization of the heat-treated glass ceramics by FESEM and TEM showed nano-crystalline spherical particles of 30-40 nm, which provided a rationale for its high transparency and good mechanical properties that may open up possibilities for newer applications.

硅铝酸锂微晶玻璃的光学和力学性能

硅铝酸锂微晶玻璃在高科技应用中有许多用途。通过对母玻璃进行控制热处理，在Li2O-Al2O3-SiO2-P2O5玻璃体系中析出了β石英或锂辉石固溶相。这些玻璃是用熔体淬火技术制备的。紫外-可见-近红外光谱法观察到该材料在可见波长范围内具有较高的透明度(>80%)。FTIR光谱表明，微晶玻璃中存在Si-O键和Al-O键。LAS玻璃陶瓷具有中等的抗弯强度(~80 MPa)和杨氏模量(~50 GPa)。通过FESEM和TEM对热处理后的玻璃陶瓷进行了微观结构表征，发现了30-40 nm的纳米晶球形颗粒，这为其高透明度和良好的机械性能提供了基本原理，可能为新的应用开辟了可能性。

期刊介绍： The Journal of Condensed Matter Nuclear Science is an open-access electronic journal that accepts scientific papers of high quality concerned with subjects relating to nuclear processes in condensed matter. Papers may focus on the results of experimental studies, theoretical studies, or a combination of these. Topics to which the journal is addressed include:- Calorimetry, energy production in metal hydrides and deuterides; Correlations, or lack of correlations, between energy production and possible nuclear products Materials science issues that are important for the development of nuclear effects in condensed matter Electrochemical issues concerning loading, surface chemistry, resistance diagnostics and other issues concerning metal hydrides and metal deuterides Observations of nuclear products, charged particles, neutrons, tritium, X-ray and gamma emission in metal hydrides Production of new elements or isotopes in metal hydrides and metal deuterides; and modification of isotopic distributions Induced radioactivity in metal deuterides and metal hydrides Accelerator experiments on metal deuterides and metal hydrides Models for nuclear processes in the condensed matter.
