Image of FIG. 1.
FIG. 1.

Electron microscopy of lithium disilicate nucleated at for 20 (up) and (down). Crystallized volume fractions are 15% and 24%, respectively.

Image of FIG. 2.
FIG. 2.

Complex plane plot of impedance data, for an annealed glass and samples heat treated at for indicated periods of time. Temperature inside graphs indicates measurement temperature. Frequency corresponding to some points is also specified. Gold sputtered electrodes were deposited in both samples’ faces.

Image of FIG. 3.
FIG. 3.

Arrhenius plot of electrical conductivity (high frequency semicircles or vitreous matrix) for the annealed sample and samples heat treated at for different periods of time. Activation energies for conduction (eV) are also presented. All the straight lines have a correlation coefficient higher than 0.999.

Image of FIG. 4.
FIG. 4.

Arrhenius plot of relaxation frequencies (HFSC) for the same samples as those in Fig. 3 (high frequency semicircles). Corresponding activation energies (eV) are also presented.

Image of FIG. 5.
FIG. 5.

Complex plane plot of impedance data of sample heat treated at for measured with platinum electrodes. Data were taken at . The frequency distribution is very similar to that obtained with the same sample, gold electrodes (Fig. 2).

Image of FIG. 6.
FIG. 6.

Arrhenius plot of electrical conductivity of crystalline lithium disilicate and of data from the low frequency semicircle obtained from samples heat treated for 20 and at .

Image of FIG. 7.
FIG. 7.

Arrhenius plot of relaxation frequency of crystalline lithium disilicate and of data from the low frequency semicircle, for same samples as those in Fig. 6.
