Lithium aluminosilicate glass-ceramics have found widespread commercial success in areas such as consumer products, telescope mirrors, fireplace windows, etc. However, there is still much to learn regarding the fundamental mechanisms of crystallizati

Barium disilicate is one of the glass-ceramic systems where internal nucleation and crystallization can occur from quenched glass upon heat treatment without requiring nucleating agents. The structural origin of the nano-clusters formed during low te

Supercooled silicate liquids exhibit several orders of magnitude increase in viscosity at the glass-transition temperature (${T}_{\mathrm{g}}$) towards the glassy state. Such a drastic dynamical slowdown leads to an abrupt change in the slope of temp

The common belief that glass structure is completely frozen-in at room temperature is challenged at both macroscopic and atomic scales. Here, we demonstrate an analytical method to elucidate the fine details of a continuous structural change of fused

The discovery of glass-ceramics, that is, the controlled crystallization of glass, by S. Donald Stookey was a mixture of serendipitous events involving both chance and exploratory research related to a practical concept. However, a combination of awa

Magnesium oxide and zinc oxide are widely used to reduce batch cost and increase the working range for the production of commercial Li 2 O–Al 2 O 3 –SiO 2 (lithium aluminosilicate), LAS, glass-ceramics. However, little work is done on the crystal

As a continuation of earlier work on thermal expansion in extruded porous cordierite honeycombs, high-temperature neutron diffraction allowed us to observe lattice strains as a function of temperature. The transfer of grain microstrain (and stress) b

Following previous study on non-microcracked porous ceramics (SiC and alumina), we studied the micro and macrostrain response of honeycomb porous microcracked ceramics under applied uniaxial compressive stress. Cordierites of different porosities wer
