Gypsum Investment Material My Dental Technology Notes

 · Quartz undergoes inversion at a temperature of 575°C from the so called low form or α quartz to the so called high form or β quartz For cristobalite conversion from the low to the high form occurs at a lower temperature of around 210°C The expansion is due to a straightening of chemical bonds to form a less dense crystal
