In Schulz's model the fractional occupancy of the octahedral sites is assumed to increase with temperature. 46(NIM) . Lld , 22 2. c are the resulting lattice-constant changes. 1 A, a change in the octahedral-site occupation of about 16% would give lattice-constant changes in agreement with the measured ones for a temperature increase from room temperature to 1000 °C. Upon extended heat treatment, lattice constants and thermal expansion of ß-eucryptite change slightly from those at room temperature.

Containing glass ceramic and the stability of this phase. A first overview of the kinetics of this phase transformation is obtained by either differential thermal analysis (DTA) or differential scanning calorimetry (DSC). The position of the transformation peak indicates the temperature range in which volume crystallization proceeds rapidly. 21 shows the DSC curve of the base gl ass of the gl ass ceramic Robax® taken at a heating rate of 5 K/min. s. crystals. In this temperature range the heating rate usually has to be reduced during ceramization to secure a uniform transformation within the whole glass ceramic object under development.

The Scientific Basis Zr02 is so strongly nucleated in the quenched condition that no boundaries of nucleation can be determined. In contrast to the behaviour of glass with variations of either Ti0 2 or Zr02, simultaneous changes in both components do not lead to a detectable shift of the nucleation area on the time axis. Thus, the delay times of all glasses are in certain - although different - temperature intervals below the limit of experimental detection. The results of investigations with glasses with varying concentrations of a single nucleating agent show that a decreasing concentration causes both a slowing down of the nucleation process and a lowering of the upper limit of nucleation.
