The Potter's Dictionary of Materials and Techniques
If 10% cristobalite is present in the body, the body will contract by the amount A to
C (approximately 1%). This is more than the glaze which is thereby compressed
by the body and unable to craze. The compression, which occurs at 226°C ...

studio firing; hence 1 100°C/2012°F is taken as the working temperature at which
the conversion of quartz to cristobalite starts when firing ceramics. The
conversion takes place slowly and is dependent on the length of time the
temperature ...

disorder and average symmetry Fd3m. It was noted that a-cristobalite can be
derived ...

Nevertheless, it is still much less common than quartz or cristobalite and
occupational exposures to tridymite could be expected in workers mining or
processing powdered igneous rocks. Tridymite (and cristobalite) is produced in
some ...

Colloidal Silica: Fundamentals and Applications
X-ray results have suggested for a long time that the structure of silica powders
most closely resembles that of cristobalite. Recent results confirm that silica gels
are built up of interconnected six-membered rings of [SiO4) tetrahedra.

cristobalite (devitrification v. vapour phase) is more-readily determined in dome
