Abstract The main purpose of the research was to explain differences between nominal and actual chemical compositions silicate-phosphate glasses in SiO 2 -P O 5 -K O-MgO-SO 3 system. materials were determined with X-ray fluorescence (XRF) analyses. Changes composition explained by examining melting processes for selected glass batches differential scanning calorimetry-thermogravimetry-related g...

The oxide glass-based anodes for lithium-ion Batteries (LiBs) still suffer from two critical drawbacks, that is, low reversible capacity and electrical conductivity. Here, we report a new way to overcome the drawbacks. Specifically, chose 50Fe2O3–50P2O5 (50Fe50P) glass as anode material LiBs, then thermally treat it at 1118 K (Tg+345 K) 0.5 h under reducing atmosphere (5 mol% H2+95 Ar). thermal...

Phosphate glasses for bioresorbable implants display dissolution rates that vary significantly with composition, however currently their mechanisms of are not well understood. Based on this systematic study we present new insights into these mechanisms. Two-stage was observed, time dependence initially parabolic and later linear, a two-stage model developed to describe behaviour. Dissolution ac...

Vitrification is the most effective method for the immobilization of hazardous waste by incorporating toxic elements into a glass structure. Iron phosphate glasses are presently being considered as matrices for the storage of radioactive waste, even of those which cannot be vitrified using conventional borosilicate waste glass. In this study, a structural model of 60P2O5-40Fe2O3 glass is propos...

A degradable phosphate glass (ICEL) and a bioactive silicate glass (CEL2) were mixed in different ratios (wt-%: 100%ICEL, 70%ICEL–30%CEL2, 30%ICEL–70%CEL2, 100%CEL2; codes 100-0, 70-30, 30-70, 0-100) and then co-sintered to obtain three-dimensional porous scaffolds by gel casting foaming. Thermal analyses were carried out on the glass mixtures and were used as a starting point for the optimisat...
