A method for the joining of silicon carbide using a cordierite glass-ceramic has been developed. Cordierite, with glass-ceramic processing, remains amorphous and wets the SiC substrate to form a strong bond when rapidly fired. Subsequent heat treatment crystallizes a multiphase interlayer with a matching bulk thermal expansion coefficient (CTE). A benchtop tape casting method for depositing joining precursor films of varying thickness is described.
