Crystallization Kinetics and Characterization of Nanostructure Mica Glass-Ceramics with Optical Transparency

Transparent glasses in a system of Li2O-MgO-SiO2-Al2O3-Fchemical constituents were prepared by melt quenching method. In the fabrication of nanocrystal glass-ceramics, controlled nucleation and subsequent crystal growth were necessary to avoid loss of transparency. It was therefore important to understand thermal properties and crystallization kinetic...

Composite Laser Ceramics by Advanced Bonding Technology

Composites obtained by bonding materials with the same crystal structure and different chemical compositions can create new functions that do not exist in conventional concepts. We have succeeded in bonding polycrystalline YAG and Nd:YAG ceramics without any interstices at the bonding interface, and the bonding state of this composite was at the atomic level, similar to the grain boundary struc...

Crystallization, Microstructure, and Viscosity Evolutions in Lithium Aluminosilicate Glass-Ceramics

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 crystallization, especially related to the evolution of viscosity as a function of the crystallization (ceramming) process. In this study, the impact of phase a...

Investigation of crystallization and sinterability properties of BaO-Al2O3-SiO2 glass-ceramics containing K2O and B2O3

BaO -SiO2-Al2O3 glass ceramics containing K2O and B2O3 were prepared using conventional melting of powered batches, quenching in water and crystallization of sintered glass. XRD patterns introducehexacelsian and celsian as two major crystallized phases in sintered glass-ceramics. Presence of K2O enhances crystallization of hexacelsianin comparison withB2O3.Observations showed sintering temperat...
