N2 - A precursor for magnesium aluminum spinel powder, composed of crystalline ammonium dawsonite hydrate (NH4Al(OH)2CO3·H2O) and hydrotalcite (Mg6Al2(CO3)(OH)16·4H2O) phases, was synthesized via precipitation, using ammonium bicarbonate as the precipitant. The precursor was characterized by differential thermal analysis/thermogravimetry, X-ray diffractometry, and scanning electron microscopy. Reactive spinel powder, which could be densified to translucency under vacuum at 1750 °C in 2 h without additives, was obtained by calcining the precursor at 1100 °C for 2 h.
