The dielectric properties of some glass-ceramic-on-metal substrates have been determined over the frequency range 500 Hz to 5 MHz using a.c. bridge techniques. The substrates consisted of cordierite-based glass-ceramics screen printed on molybdenum. For glass layers of thickness greater than 100-mu-m both the permittivity, epsilon' and the dielectric loss, epsilon", are frequency independent over this frequency range at room temperature giving the value of epsilon' = 6.5 and tan-delta = 8 x 10(-3); the room-temperature data are consistent with the universal law of dielectric response. The variation of permittivity with temperature has also been examined and, below 120-degrees-C, the temperature coefficient [(epsilon' - 1) (epsilon' + 2)]-1 (partial derivative-epsilon'/partial derivative T)p, was found to be 1.3 x 10(-5) K-1. The results are compared with those previously reported for Al2O3 and AIN substrates.
