EFFECT OF TiO2 ADDITION ON BONDING STRENGTH OF CaO-P2O5 Na2O-TiO2 BIOACTIVE GLASS CERAMIC COATING
The effect of titanium dioxide addition on bonding strength of CaO-P2O5 -Na 2O-TiO2glass-ceramic system was investigated as a coating on titanium substrate. Thus, different amounts of TiO2 (2, 3.5 and 5mol %) were added to the base glass batch composition. The prepared glaze slips were applied on the substrate by dip coating method, dried and then heat treated at various temperatures. After tha...
متن کاملCharacterization of bioglass ceramic after addition of fluorine in Na2O-CaO-SiO2 system
Bioactive glass formed on the base sample (Go) of 45S5 system with fluorine additives samples were prepared by melt quenching method. The glassy samples were subjected to DTA for determining temperatures at which phase transition occur. FTTR spectroscopy shed a light on the sorts of compounds, their structure as well as their functional groups. The crystalline nature of samples was confirmed by...
متن کاملEffect of Alumina Incorporation on the Surface Mineralization and Degradation of a Bioactive Glass (CaO-MgO-SiO2-Na2O-P2O5-CaF2)-Glycerol Paste
This study investigates the dissolution behavior as well as the surface biomineralization in simulated body fluid (SBF) of a paste composed of glycerol (gly) and a bioactive glass in the system CaO-MgO-SiO₂-Na₂O-P₂O₅-CaF₂ (BG). The synthesis of the bioactive glass in an alumina crucible has been shown to significantly affect its bioactivity due to the incorporation of aluminum (ca. 1.3-1.4 wt %...
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 ...
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...
