Lithium aluminosilicate (LAS) glass-ceramics: a review of recent progress

Abstract

The lithium aluminosilicate system (LAS) is being explored for almost seven decades due to its anomalous and attractive properties (especially low/negative thermal expansion and fast ion conduction) and its commercial significance in consumer as well as strategic sectors. This review introduces current commercial applications of LAS systems, necessary background science, structural features of different LAS crystal systems, including their polymorphs and solid-solutions, and the origin of unusual properties. Significant emphasis is provided on processing transparent, nanocrystalline, low thermal expansion glass-ceramic (LEGC), the role of chemical constituents and additives, the effect of heat-treatment, and microstructural evolution while processing LEGC. Detailed discussions are provided on the following areas: LAS matrix composites, chemical strengthening of glass and glass-ceramic, low temperature co-fired ceramics (LTCC) and associated joining technologies (hydrolysis catalysis bonding, anodic bonding, brazing, etc.) that would further extend the application portfolio of LAS system.

Harnessing ion–dipole interactions: a simple and effective approach to high-performance lithium receptors

“…1,2 Moreover, it is utilized to enhance strength and thermal stability in the ceramics and glass industries and improve lubricants' viscosity. 3,4 The most signicant application of Li + lies in its indispensable role as a key component in lithium-ion batteries. [5][6][7][8] The ongoing global energy transition from fossil fuels to renewable sources has precipitated a Li + supply crisis, highlighting the imperative to develop novel technologies for extracting and enriching Li + from natural resources and anthropogenic waste.…”

Effect of Gold Nanoparticles on the Crystallization and Optical Properties of Glass in ZnO-MgO-Al2O3-SiO2 System

“…The phases formed in glass-ceramics can be oxide and non-oxide crystallites, metal nanoparticles (NPs), clusters, or semiconductor quantum dots [4]. The precipitation of different crystallites in transparent glass-ceramics is being actively studied to develop new light-emitting and laser media [5][6][7], materials with controlled values of the thermal expansion coefficient [8], and high-strength transparent cover materials [9][10][11]. Similarly, glass-ceramics based on metal NPs (mainly silver or gold) are in great demand as new nonlinear optical and plasmonic materials [12][13][14][15][16].…”

“…In recent years, rare‐earth (RE)‐doped GCs have been endowed with more and more interesting characteristics. These characteristics make them widely used in biomedicine, electronic information, mechanical construction, military affairs, and other fields 1–3 . But up to now, single functional materials have been widely studied.…”

“…These characteristics make them widely used in biomedicine, electronic information, mechanical construction, military affairs, and other fields. [1][2][3] But up to now, single functional materials have been widely studied. With the development of science and technology, many new materials are required to gradually develop toward miniaturization, integration, and light weight.…”
