Experimental work on the carbonation of brucite has been carried out in the temperature and pressure ranges of 50−120 °C and 1−10 bar respectively, using concentrated CO₂ and simulated flue gas. At 120 °C hydromagnesite and trace amounts of magnesite were identified. Highly to semi-ordered dypingite like-phases and nesquehonite, coexisting with a possibly amorphous carbonate phase, were identified at 50 °C. The dehydration temperatures and chemical composition of these amorphous phases are very close to those of crystalline, stoichiometric nesquehonite. This probably amorphous phase nourishes the late formation of dypingite. This latter mineral gradually undergoes a cell shrinkage due to the partial loss of molecular waters, becoming structurally more ordered as the carbonation reaction proceeds. It remains unclear whether nesquehonite formed directly from brucite or from the crystallization of an amorphous precursor. However, nesquehonite is precursor of dypingite and/or the possibly amorphous phase. Only crystalline carbonate phases were observed at 120 °C. Concentrated CO₂ experiments yielded the highest amounts (up to 37 wt.%) of CO₂ sequestered at 10 bar and 16 h of reaction, reaching an almost complete carbonation of brucite (>98 %). On the other hand, flue gas experiments results showed higher amounts of CO₂ sequestered per unit of CO₂ partial pressure than with concentrated CO₂.

使用浓CO ₂分别在50-120°C和1-10 bar的温度和压力范围内进行了水镁石碳酸化的实验工作。和模拟烟气。在120°C时，发现菱镁矿和痕量菱镁矿。在50°C时鉴定出高度至半有序的dypingite类相和nesquehonite与可能的无定形碳酸盐相共存。这些无定形相的脱水温度和化学组成非常接近于晶体化学计量的水蒙脱石。这种可能为非晶态的相养育了锂蒙脱石的后期形成。由于分子水的部分损失，后一种矿物逐渐经历了细胞收缩，随着碳酸化反应的进行，其结构在结构上更加有序。尚不清楚水镁石是​​直接由水镁石形成还是由无定形前体的结晶形成。但是，水松石是锂蒙脱石和/或可能的无定形相的前体。在120℃下仅观察到结晶碳酸盐相。浓CO_2个实验在10 bar和16 h反应中产生的最高量（最高37 wt。％）的CO ₂隔离，达到了几乎完全的水镁石碳酸化（> 98％）。另一方面，烟道气实验结果表明，每单位CO ₂分压中滞留的CO ₂量高于浓CO ₂。
