Characterization of the high-temperature modifications of incommensurate tridymite L3-To(MX-1) from 25 to 250∑C
Characterization high-temperature modifications incommensurate tridymite L3-To(MX-1)
2012/4/1
Incommensurate tridymite L3-TO(MX-1) shows a cascade of five phase transitions at 65,110, 150, 200, and 380 8C upon heating. The X-ray diffraction patterns were investigated with a Buerger precession ...
