采用热重法测定了部分al2o3 - cao - mgo - sio2季铵盐渣的氢溶解度。工作的重点是确定具有较低的sio2浓度的炉渣的水容量，这与工业实践有关。大部分实验是在1747 ~ 1827 K的温度区间和157毫巴的水压下进行的。用淬火技术验证了实验的可靠性。人们发现温度对水的溶解度的影响可以忽略不计。矿渣的成分似乎对水容量没有显著影响。然而，当炉渣成分接近CaO饱和时，溶解度显著增加。
A thermo-gravimetric technique was used to determine the hydrogen solubilities of some Al2O3-CaO-MgO-SiO2quaternary slags. The focus of the work was to determine the water capacities in slags having lower SiO2concentrations, which were relevant to industrial practices. The majority of the experiments were carried out in the temperature interval 1747 to 1827 K with water pressure of 157 mbar. The reliability of the experiments was confirmed using a quenching technique. The temperature was found to have a negligible effect on the water solubilities. The composition of the slag did not seem to significantly affect the water capacity. However, as the slag composition approached CaO saturation, a considerable increase of the solubility was noticed.
