Effective role of CaO/P2O5 ratio on SiO2-CaO-P2O5 glass system
In the present work, the effect of the CaO/P2O5 ratio on the composition of sol-gel synthesized 58SiO2-(19 - x)P2O5-(23 + x)CaO (x = 0, 5, 10 and 15 mol%) glass samples was studied. Further, the effect of NBO/BO ratio on hydroxy carbonated apatite layer (HCA) forming ability based on dissolution behavior in simulated body fluid (SBF) solution was also investigated. CaO/P2O5 ratios of synthesize...
متن کامل[Basic studies on CaO-P2O5-MgO-SiO2-CaF system glass ceramics. 2. Ultrastructural study on interface between culture cells and glass ceramics].
The aim of this study was to determine biocompatibility of glass ceramics and adhesion of cultured cells to glass ceramics. Four established cultured cell lines, human fibrosarcoma cells (HT-1080), human gingival carcinoma cells (Ca9-22), human osteosarcoma cells (NY) and mouse osteoblasts (MC3T3-E1), were used. For phase-contrast and electron microscopic observation they were cultured on subst...
متن کاملDeposition of Nano-Crystalline Fluor-hydroxyapatite Coatings on Titanium Substrates via Sol-Gel Method
In this investigation, fluor-hydroxyapatite (FHA) film was deposited on a titanium substrate by sol-gel method. Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol solutions were used respectively as P, F and Ca precursors. Typical apatite structures were obtained for all coatings after dipping and subsequent heat treatment at 550, 700 and 800 ºC, the coating layers were ...
متن کاملSiO2-CaO-P2O5 Bioactive Glasses: A Promising Curcuminoids Delivery System
In this paper, we report the study of the loading and the release of curcuminoids by bioactive glasses (BG) and mesoporous bioactive glasses (MBG). Through a detailed spectroscopic study, it was possible to determine the amount and the type of molecules released in water and in simulated body fluid (SBF). In particular, curcumin and K2T21 show a good ability to be released in di-keto and keto-e...
متن کاملStudies on preparation and characterizations of CaO-Na2O-SiO2-P2O5 bioglass ceramics substituted with Li2O, K2O, ZnO, MgO, and B2O3
-The bioactive glass 45S5 (Hench glass), having composition 45 SiO2 24.5 Na2O 24.5 CaO -6 P2O5 (wt %) were prepared with substituted Li2O, K2O, ZnO, MgO, and B2O3 by conventional melting process in an electric globar furnace at 1400±10 OC. The Controlled crystallization were carried out to convert the bioglasses to their corresponding bioglass ceramics. Nucleation and crystallization regimes we...
