To reduce the likelihood of thermal shock of a ceramic material, the external conditions must be altered to the degree that cooling or heating rates are reduced and temperatures gradients across a body are minimized. Equation 19.9 states: $TSR = \frac{σ_{f}k}{Eα_{l}}$ This denotes that by reducing the $α_{l}$ of a ceramic material, resistance to thermal shock will be increased.
