HfO 2（am）的溶解度测定在不同的平衡期从过饱和和欠饱和的方向，在非常酸性到碱性溶液（0。1 mHCl至3.2mNaOH）和浓度范围从非常稀至高达5.59mNaCl溶液中以及pC（H）+范围从1至4中进行，以获得Hf 4 +-Cl--Na+-H+-OH-H 2 O体系的可靠热力学数据。研究表明，迅速达到平衡（
The solubility of HfO2(am) was determined at different equilibration periods from the over- and undersaturation directions, in very acidic to basic solutions (0. 1 m HCl to 3.2 m NaOH), and in NaCl solutions ranging in concentrations from very dilute to as high as 5.59 m and in a pC(H)+ range from I to 4 to obtain reliable thermodynamic data for the Hf4+-Cl--Na+-H+-OH-- H2O system. The studies indicate that equilibrium is reached rapidly (
