Abstract: There is disclosed a sintered, alpha-cordierite solid solution glass-ceramic body in which the properties of coefficient of thermal expansion and modulus of rupture are stabilized and controlled by using a combination of two dopants in the glass during sintering and crystallization. There is further disclosed the method of producing such bodies, and controlling such properties, through the use othe two dopants.
