چکیده

Abstract Using Raman spectroscopy in conjunction with X-ray diffraction (XRD), transmission electron micrographs (TEM-EDP), and scanning microscopy (SEM), the local environment of Te atoms crystallization behavior glasses system chemical formula x Ag 2 O. (100 − )TeO (25 ≤ 50 mol%) have been examined. Crystalline structure was evident XRD spectra containing 40 mol% TeO . On other hand, an amorphous has observed lower O concentrations (25, 30, 35 mol%). Thermal heating could be used to crystallize glasses’ structure. DSC measurements, treatment's temperature controlled. The species good crystallinity include 4 9 5 results TEM EDP, as well both SEM XRD, revealed that enriched O, crystalline clustered were formed. data proved is improved a result formation 3 units nonbridging oxygen bonds. In compositions less than mol%, plays role glass modifier. At higher concentrations, it building clusters types.

CRYSTALLIZATION AND SINTERABILITY BEHAVIOR OF BIORESORBABLE CaO-P2O5-Na2O-TiO2 GLASS CERAMICS FOR BONE REGENERATION APPLICATION

Abstract:Some types of glass and glass ceramics have a great potential for making bone tissue engineering scaffolds, drug carrier and bone cements as they can bond to host bone, stimulate bone cells toward osteogenesis, and resorb at the same time as the bone is repaired. Calcium phosphate glass ceramics have very attractive properties that allow them to use in bone tissue engineering. Calcium ...

Addition of Alumina to Nanoporous Calcium Titanium Phosphate Glass-Ceramics and its Effects on Crystallization Behavior

Microporous Calcium Titanium Phosphate glass-ceramics have many uses in high-tech industries. For example, they have applications in catalysts industry. In this study, different molar percentages of alumina were added to a glass with P2O5 30, CaO 45, TiO2 25 (mol%) composition. The samples were melted at 1350°C and crystallization heat treatment was performed on...

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...

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...
