The causticization behaviour of Na2CO3 with rock‐salt type oxide, Mg2(1‐x/(2+x) O (M = Al3+ and Fe3+, x = 0.2 and 0.33), produced by the thermal decomposition of hydrotalcite‐like layered double hydroxide was investigated at 30–60°C. The degree of causticization increased with increasing the molar ratio of [rock‐salt type oxide]/[Na2CO3] and increasing the temperature but decreased with increasing the initial concentration of Na2CO3. The causticization behaviour could be adequately described by the equation of anion exchange equilibria between CO32‐ and OH for layered double hydroxide.
