Low-temperature phase transition and transport properties of β-Cu2−xSe fabricated using hydrothermal synthesis and evacuating-and-encapsulating sintering

Author(s): , , ,

Materials of β-Cu2−xSe were fabricated by using hydrothermal synthesis followed by evacuating-and-encapsulating sintering. These materials were then characterized using powder X-ray diffraction, field-emission scanning electron ...

Fabrication of porous silica ceramics by gelation-freezing of diatomite slurry

Author(s): , , ,

Using a gelation-freezing method, diatomite-derived porous silica ceramics with high porosities up to 90% were fabricated. Diatomite particles contain large numbers of meso- and micropores, intrinsically reducing the thermal conductivity. In ...
