Abstract:
A glass-ceramic having at least two crystal phases, wherein at least one crystal phase has a positive temperature dependence of the resonance frequency τf, at least one crystal phase has a negative temperature dependence of the resonance frequency τf and the glass-ceramic has a resulting temperature dependence of the resonance frequency τf of 0 ppm/K with a maximum deviation of +/−20 ppm/K, is described. Furthermore, a process for producing such a glass-ceramic and the use of the glass-ceramic are described.
