We develop the rheology of a dilute granular gas mixture. Motivated by the interaction of charged granular particles, we assume that the grains interact via a square shoulder and well potential. Employing a kinetic theory, we compute the temperature and the shear viscosity as a function of the shear rate. Numerical simulations confirm our results are above the critical shear rate. At a shear rate below a critical value, clustering of the particles occurs.
