Transparent Glass Ceramics Based On Zno Crystals

The average crystal size obtained from the x ray diffraction data was found to range between 14 and 35 nm.

Transparent glass ceramics based on zno crystals.

The materials can be highly transparent with zno crystal sizes on the order of 5 20 nm dispersed uniformly throughout an alkali aluminosilicate glass. At 860 c traces of eu oxyapatite appeared in addition to zno nanocrystals. Transparent glass and glass ceramics containing zno nanocrystals were successfully synthesized through melt quenching method. Glass ceramics based on hexagonal zno crystals can be obtained in the sio 2 al 2 o 3 zno k 2 o system.

38 45 47 at elevated temperatures a disordered and then ordered pyrochlore type structure is. The materials can be. As the b 2 o 3 is replaced by zno gradually the glass transition temperature changed slightly while the onset crystallization temperature and the crystallization peak temperatures shifted to lower values. Controlling the crystallization condition can allow the formation of highly transparent zno doped gcs.

Pinckney reported the first zno precipitated tgc based on a parent glass of sio 2 al 2 o 3 zno k 2 o. Transparent glass ceramics based on nano sized crystals of re titanates and titanates zirconates. Transparent glass ceramics gcs based on co2 zno nanocrystals mean diameter 11 nm are synthesized on the basis of cobalt doped glasses of the k2o zno al2o3 sio2 system. Download citation transparent glass ceramics based on zno crystals glass ceramics based on hexagonal zno crystals can be obtained in the sio2 al2o3 zno k2o system.

When las or mas glasses nucleated by tio 2 or zro 2 are doped with re ions re 2 ti zr 2 o 7 crystals with the defect fluorite structure precipitate. This is one of the few transparent yet relatively highly crystalline materials based on a semiconductor crystal phase. Transparent zincite zno glass ceramics were obtained by secondary heat treatments at 680 860 c.
