Solution A was prepared by dissolving Mg(NO3)2 (C150 - 126,76 g) and Ni(NO3)2 ( S90 - 3,5911 g) in 500 mL mqH2O. Solution B was prepared by dissolving 75 mL of NH3 (25%) in 1000 mL mqH2O. In the Optimax, A (300 g) and B (300 g) were dosed at constant rate (10 g/min) in 200 mL mqH2O, at 60°C, aged for 1 h. Pumps=70%. Inputs=1A and 2B. The product was filtered once (15A) and then washed 3 times with 360 mL mqH2O, separated by centrifugation as solid was too fine and passing through even the 15A filter, big beakers, 5000 rpm, 15 min. Conductivity last washing= 0,06 mS/cm Dried at 80°C overnight. During the synthesis, the pH stayed around pH=8,5.
