Borate glass ceramics doped with Eu3+ were prepared by the melt crystallization method. The crystalline phase Al4B2O9 in glass-ceramics was determined X-ray diffraction.. optimal doping concentration of obtained emission spectrum, and color purity corresponding to calculated. Compared samples, it is proved that have high luminescence intensity.

We report on a comparative study of transparent Fe:MgAl2O4 (spinel) ceramics and nanophase Fe:MgAl2O4-based glass-ceramics. The 0.1 mol% was synthesized by hot pressing (at 1500 °C/50 MPa) powders obtained the sol-gel method using LiF as sintering aid. ceramic is single-phase material (cubic structure, sp. gr. Fd3‾m, = 8.083 Å) with mean grain size ~50 μm. exhibits broadband transparency 0.2–6....

Glass-ceramics (GCs) are materials obtained from the crystallisation of functional phases in glass, and have a structure that the crystallised phase embedded in the glass matrix. Glass-forming oxides are commonly added to the functional phases to improve the stability of precursor glass; however, the issue of glass-ceramics permitting the presence of residual phases resulting from addition is r...

The stabilization of inorganic waste of various nature and origin, in glasses, has been a key strategy for environmental protection for the last decades. When properly formulated, glasses may retain many inorganic contaminants permanently, but it must be acknowledged that some criticism remains, mainly concerning costs and energy use. As a consequence, the sustainability of vitrification largel...

An innovative route is reported to fabricate nano-particles in aqueous solution from oxyfluoride glass by the thermal induction and corrosion treatment in this letter. The investigations of X-ray diffraction and transmission electron microscope based on nano-particles in glass ceramics (GCs) and aqueous solution indicate that the nano-particles formed in glass matrix during the thermal inductio...

Metal and in particular noble metal nanoparticles represent a very special class of materials which can be applied as prepared or as composite materials. In most of the cases, two main properties are exploited in a vast number of publications: biocompatibility and surface plasmon resonance (SPR). For instance, these two important properties are exploitable in plasmonic diagnostics, bioactive gl...

The manufacture of sintered glasses and glass-ceramics, glass matrix composites, and glass-bounded ceramics or pastes is often affected by gas bubble formation. Against this background, we studied sintering and foaming of barium silicate glass powders used as SOFC sealants using different powder milling procedures. Sintering was measured by means of heating microscopy backed up by XPD, differen...
