Studies 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...
متن کاملPREPARATION OF Fe/GLASS COMPOSITE BY REDUCTION OF Na2O– Fe2O3–B2O3–SiO2–ZnO GLASS AND GLASS CERAMICS
In the present study, the feasibility of α-Fe ferromagnetic phase formation in glass and glass-ceramic by reduction in hydrogen atmosphere have been investigated. The glass with the composition of 35Na 2 O–24Fe2O3–20B 2O3 – 20SiO 2 –1ZnO (mol %) was melted and quenched by using a twin roller technique. As quenched glass flakes were heat treated in the range of 400-675 °C for 1-2 h in h...
متن کاملPhotocatalytic degradation of an azo textile dye with manganese-doped ZnO nanoparticles coated on glass
Mn doped ZnO nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. Mn doped ZnO nanocomposite thin film was characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

متن کاملThermal analysis of Li2O TeO2 glass
The thermal properties of 0.30Li2O 0.70TeO2 glass are studied. Speci®c heat, Cp, is measured in the 170°C < T < 270°C interval. The Einstein temperature, hA 840 K, is determined from the temperature course of Cp. In the glass transition interval, the heat capacity undergoes an S-shaped transition from the value, Cgl, of the glass to that of undercooled melt, Cp. It is found that Cgl=Cp 0:62. ...
