When concentration of the additive in sodium aluminate solution reach 0.175 g/L, the average size of ATH is 3.9 μm. The infrared spectra analysis show......
. The equation of the specific heat capacity as a function of total alkalinity, αK and temperature was constructed for sodium aluminate solution. The error between the results calculated from this equation and experimental values derived from the literature is 0.014. The apparent molar specific heat capacities (cpΦ) for sodium aluminate solution were also calculated, and the results show......
