混凝被认为是一个类似于化学反应的速率过程，并计算了不同含量的二氧六环和水沿着氯化钾作为电解质的混合物中混凝过程的活化能E和空间因子P的值。研究表明，随着色散介质介电常数的降低，E和p值有减小的趋势，当使用较多的色散介质时也是如此。结果表明，E值与表面性质有关，是决定憎液溶胶稳定性的主导因素。
Coagulation has been considered to be a rate process similar to a chemical reaction and the values of the energy of activationE and the steric factorp has been calculated for the process of coagulation in the mixture of varying amount of dioxan and water along with the potassium chloride used as a coagulating electrolyte. It has been observed that with the lowering of dielectric constant of the dispersive medium the values ofE andp have a tendency to decrease, this is also the case when the greater quantities of coagulating electrolyte are used. It has been concluded thatE is related with the surface properties and is the guiding factor for the stability of lyophobic sol.
