Sintering and accompanying microstructural evolution is inarguably the most important step
in the processing of ceramics and hard metals. In this process, an ensemble of particles is …

The need for materials for demanding optical applications has engendered a resurgent
interest in transparent ceramics. Transparent polycrystalline magnesium aluminate spinel is …

Grain boundaries exhibit phase-like behavior in which their structure, chemistry and
properties may change discontinuously at critical values of thermodynamic parameters such …

The overview focuses on inherent optical properties, governed by composition and the state
of the crystal lattice, and on the interference of these properties with the microstructural …

Solid‐state conversion of single crystals from polycrystalline materials has the advantages of
cost‐effectiveness, chemical homogeneity, and versatility over the conventional melt growth …

This paper demonstrates that fine‐grained (2–3 μm), transparent Nd: YAG can be achieved
at SiO2 doping levels as low as 0.02 wt% by the sinter plus hot isostatic pressing (HIP) …

Hot isostatic pressing (HIP) has unique advantages in the preparation of high-density, fine-
grained ceramics. In this work, 1.0 at.% neodymium-doped yttrium aluminum garnet (Nd …

This paper examines the influence of SiO2 doping on densification and microstructure
evolution in Nd3xY3− 3xAl5O12 (Nd: YAG) ceramics. Nd: YAG powders were doped with …

Realizing the high brightness solid-state lighting with the emission spectra similar to that of
sun light is significantly challenged by the inherent deficiency of the luminescence spectrum …

Transparent ceramics have been in the spotlight as advanced optical ceramic materials for
the last two decades, both as optically transparent materials with excellent mechanical …
