摘要：

The densities of mixtures of aqueous lithium and potassium hydroxides were measured up to 3 molal, at 373, 423 and 523 K at pressures close to saturation. The partial molar volumes were calculated and the coefficients of the Pitzer equation for the mixtures were obtained. The mixing volume is positive at 373 K while at higher temperatures the mixture is ideal within experimental error, probably as a result of association of the lithium hydroxide.
