摘　　要：The hydrolytic polymerization of Cr3+ at relative high concentrations have measured by microcalorimetric method. The thermogram have determined using the 2277 Thermoal Activity Monitor. The heat of reaction (△rHm■), the hydrolysis equilibrium constans (K■) and thermodynamical function (△rGm■、△rSm■) at different temperatures have been calculated.The hydrolytic polymerization of Cr3+ at relative high concentrations have measured by microcalorimetric method.
