چکیده
Sb distribution in the phases of SiO2 saturated Sb-Fe-O-SiO2-CaO system was determined for first time through hightemperature experiment and quenching techniques, followed by Electron probe X-ray microanalysis (EPMA) air (Ptot = 1 atm, PO2 0.21 atm). The were quantified temperature range 900?C-1200?C effects Fe/SiO2 (mass fraction) CaO/SiO2 on Sb2O3 content investigated at 1200?C. results indicated that Sb-containing phase primarily existed solid solution With increase from 1100?C to 1200?C, increased drastically 7.52 wt% 17.36 wt%. Lowering values smelting process effectively reduced slag. verification suggested antimony slag 0.57 wt%, crude yield rate lower than 4%, grade beyond 94 which meant reduction could be achieved.

SiO2-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...

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...
