"Densities of concentrated alkaline aluminate solutions at temperatures (323 to 573) K and 10 MPa pressure." . "Densities of highly alkaline sodium aluminate solutions have been measured by vibrating-tube densimetry over the temperature range 323 to 573 K at a pressure of 10 MPa. Ionic strengths, I, of these mixed solutions were from 1 to 6, and the degree of substitution of hydroxide by aluminate, R, ranged from 0.1 to 0.4, where R = mA/m and mA and m () I) are the aluminate and total molalities, respectively. Apparent molar volumes, V\u03C6, derived from the density data for the (NaOH + NaAl(OH)4)(aq) solutions, were found to follow Young?s rule; that is, they depended linearly on the level of substitution of aluminate for hydroxide at all temperatures. The slopes of the Young?s rule plots were independent of ionic strength at a given temperature but depended linearly on temperature. It is therefore possible to model V\u03C6 (and hence the densities) of ternary (NaOH + NaAl(OH)4)(aq) mixtures using only two parameters in addition to those needed for the correlation of the binary NaOH(aq) solutions.
