Procedure

Sodium citrate dihydrate was dissolved in nano-pure water to obtain 2.8% (w/v) sodium citrate. Ga(NO3)3.9H2O was added to the solution to obtain 2.8% (w/v) Ga(NO3)3. To the gallium-containing solution, ethanol was added to give a final composition of 10% (v/v). The mixture was spray-dried at Tin/Tout=80/60° C., q=0.5 mL/min, and Patm=15 psi. The powder was collected under controlled temperature and humidity of 30° C. and <5% RH, respectively. The residual moisture content was 6.3% (w/w).
