Table 1: Composition of the magnesium silicate samples used for reflection measurements derived by EDX measurements in the SEM and TEM.
Table 2: Diagnostic spectral parameters of the 10 and 20 $\mu$ m bands of amorphous magnesium silicates based on calculations of the absorption cross section per unit volume $C/\langle{V}\rangle$ (in cm^-1) for small spheres (Sph.) and a continuous distribution of ellipsoids (CDE) for particles in the Rayleigh limit. $\lambda$ and A represent the peak position in $\mu$ m and the absorption cross section per unit volume $C/\langle{V}\rangle$ in cm^-1, respectively. W stands for the FWHM of the bands. The band ratio has been calculated by dividing the intensity of the 20 $\mu$ m band by the intensity of the 10 $\mu$ m band.
Table 3: Activation energies of crystallization $E_{\rm a}/k$ determined for differently produced magnesium silicates.
