Based on the CaO-Na2O-Fe2O3-FeO-B2O3-SiO2 system, the ferrimagnetic glass-ceramic has been prepared for hyperthermia application by aqueous aolution-melt method. Using the aqueous solution solvent evaporation, we obtained the molecular-scale homogenously glass precursor. The precursor was completely melted in a lidded platinum crucible placed in an electric furnace at 1480°C for 1h and then annealed in a furnace at 550°C for 40min.The annealed glasses were heat treated at 1050°C for 2h to obtain the glass-ceramics. The crystallization of the glass systems with different component has been systematically investigated by using XRD, TG, as well as Vibrating Sample Magnetometer (VSM). The glass-ceramics with B2O3=3.0wt% show a strong magnetic, which contains highest value of specific saturation magnetization of 28.34A•m2/kg.

Fluorophosphate Glass

A new fluorophosphate (Na2O + NaF)–TiO2–B2O3–P2O5–ZrF4 (NTBPZ) glass and glass–ceramic have Na-ion conductivities up to 7 × 10−9 S cm−1 and 3 × 10−5 S cm−1, respectively. Na-ion conductivity improves due to formation of conductive phase NaTi2(PO4)3.
