The stoichiometric amount of gallium-(III)-nitrate hydrate (5.031 g) was dissolved in 80 mL of deionised water to yield gallium nitrate solution. On the other hand, 1.27 g of ammonium metavanadate were dissolved in 100 mL of deionised water at 80° C. The two solutions obtained were mixed under continuous stirring and the pH of the mixture obtained was adjusted to 7 by adding 24% aqueous ammonia solution. A precipitate formed and the suspension obtained was stirred for another half an hour and filtered. The solid obtained was washed several times with deionised water and dried at 120° C. overnight. 2 g of gallium vanadate were obtained and analytically characterised.
