Abstract:

The time dependence of the ordering and disordering of Al and Si in sanidine is described within the framework of the kinetic rate laws developed in papers I and II of this series. It was found that the relevant order parameter Q_t is homogeneous and non-conserved. The rate law is:

$frac{{dQ_1 }}{{dt}} = - frac{1}{tau }exp(--Delta G_a^* /k_B T)frac{{delta G_0 }}{{delta Q_t }}.$
