Preparation of NASICON-type Titanium Phosphate Mg0.5Ti2(PO4)3 from Magnesium Borophosphate Glasses
Original language description
Preparation of the Mg0.5Ti2(PO4)3 NASICON-type material by controlled crystallisation of magnesium titanium borophosphate glasses of the composition 30MgO.20B2O3.xTiO2.(50-x)P2O5 (x=0-25 mol% TiO2) followed by subsequent acid leaching of crystalline products was studied. All prepared glasses crystallise under heating within the temperature range of 650-870°C and the surface nucleation is the prevailing process. The lowest tendency towards crystallisation has the glass with 5 mol% TiO2. X-ray diffractionmeasurements showed that major compounds formed by glass crystallisation were Mg(PO3)2, Mg2P2O7, TiP2O7, BPO4 and Mg0.5Ti2(PO4)3. Crystalline samples, prepared by heat treatment of the glasses at 900°C, were leached with 2 m HCl aqueous solution at roomtemperature. Changes in the XRD patterns of TiO2-containing crystalline samples revealed that hydrochloric acid selectively dissolves mostly Mg2P2O7. The maximum output of Mg0.5Ti2(PO4)3 with respect to the leachability of the other phas
