Sintering Behavior and Properties of Iron-Rich Glass-Ceramics
Iron-rich glass-ceramics were obtained by the sintering of two glass powders, labeled G1 and G2, at heating rates of 5° and 20°C/min followed by an isothermal step in the 850°–1050°C temperature interval. The sintering process was evaluated by the linear shrinkage; the closed porosity was estimated by density measurements; the structure and the morphology of the glass ceramics were observed by ...
متن کاملBioactivity of Sodium Free Fluoride Containing Glasses and Glass-Ceramics
The bioactivity of a series of fluoride-containing sodium-free calcium and strontium phosphosilicate glasses has been tested in vitro. Glasses with high fluoride content were partially crystallised to apatite and other fluoride-containing phases. The bioactivity study was carried out in Tris and SBF buffers, and apatite formation was monitored by XRD, FTIR and solid state NMR. Ion release in so...
متن کاملInvestigation 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...
متن کاملInduced crystallization porosity and properties of sintereds diopside and wollastonite glass-ceramics
diopside (CaO·MgO·2SiO2) and wollastonite (CaO·SiO2) glass-ceramics, forming ∼60% crystal phase and ∼40% albite-like Na2O·Al2O3·6SiO2) residual glass were studied. Two other diopside glass-ceramics with higher Na2O and Al2O3 content were also investigated. The phase formation was estimated by DTA, XRD and pycnometry, while the densification process was evaluated by porosity variations, ilatomet...
متن کاملCRYSTALLIZATION 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 ...
