water in cellosolve=2-ethoxyethanol dropwise addn. of H2O in 2-ethoxyethanol to soln. of Ti and Mg compds. at room temp. with stirring; evapn., heating stepwise in air up to 500°C, then 3 h at 700°C yields metastable Mg2TiO4, which decomposes at higher temp. into MgO and MgTiO3 and reforms on sintering above 1350°C as thermodynamically stable compd.;
