Detailed Description

Sintering model of Koch and Friedlander (1990). The characteristic time for sintering is given by.

$\tau = c_s d_{p_i}^n T^m \exp(T_a/T \cdot [1 - d_{p,min}/d_{p_i}])\;.$

Note that the correction factor in the exponential function can be eliminated by setting $d_{p,min}$ to zero which is done by default.
