desulfurization of plain carbon steel by cao-al2o3-sio2 and cao-al2o3-sio2-x (x = na2o, sro) synthetic slags
synthetic slag process decreases sulfur and phosphorus contents of steel, improves inclusion removal, protects steel from atmosphere and prevents temperature drop of the liquid steel in the ladle. in this study, the synthetic slags of ternary cao-al2o3-sio2,and quaternary cao-al2o3-sio2-na2o and cao-al2o3-sio2-sro systems were pre-melted and then were kept in contact with the liquid steel in a ...

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 ...
متن کاملPREDICTION OF ACTIVITIES OF OXIDE COMPONENTS IN THE MULTICOMPONENT LIQUID SYSTEM Fe0-MgO-CaO-Na2O-Al01.5-Si02;
Calculation of chemical equilibria involving a liquid requires a full knowledge of chemical potentials (or activities) of all the oxide components present in the liquid phase. This is a rigorous requirement compared to that for solid compounds, where only total free energies need to be known in order to calculate their stabilities relative to other compounds; obviously the difference stems from...
