Study on hydrothermal synthesis dynamics of xonotlite spherical particles
The xonotlite crystals were synthesized via the hydrothermal synthesis manner from CaO and SiO2 as the raw materials with their Si/Ca molar ratio of 1.0.The products were characterized by XRD and SEM techniques to investigate their crystalline phases and morphologies.Hydrothermal synthesis dynamics of xonotlite spherical particles was explored by masterly measuring the pH and the calcium concentrations of product slurries synthesized at various reaction temperature in this paper.The results indicated that the calculated values of the products quality at various reaction temperatures were consistent with the measured values.Based on chemical reaction kinetic,using fourth-order Runge-Kutta method,spline interpolation and least-squares fitting method,the dynamic relationship of xonotlite spherical particles synthesized via hydrothermal synthesis process is of-dcA/dt=kcA0.9.
