摘要
The supersaturated solution of Li2O·2B2O3-H2O containing 26.8% Li2O·2B2O3 were prepared and kept at 20℃ The crystallization processes of Li-borates from the solution has been studied with the kinetic method.Two Li-borates, Li2B4O7·3H2O and LiBO2·8H2O crystallized out from Li2O·2B2O3-H2O solution. With the aid of simplex method and digital integration as well as RungeKutta digital solution of differential equation system, the experimental data were fitted and the crystailization kinetic equation of the first solid phase was obtained. The crystallization reaction processes of the two Li-borates were also discussed.
