About
11-BM has a dedicated Cyberstar Hot Gas Blower. This can be used to heat small diameter capillary samples from ambient temperature to ~ 950 °C
About
Temperature Range and Ramp Rate.
- ambient temperature to ~ 950 °C
- Max ramp rate on heating & cooling is 5 deg C/min (300 C/hour)
Users should plan experiments to incorporate these heating and cooling ramp times.

Al2O3 Thermal Expansion
In-situ calibration of the hot gas blower was performed (summer 2012) using the known thermal response of Al2O3 a & c unit cell parameters as a function of temperature.
11-BM calibration results kindly shared by Jae-Hyuk Her, GE Global Research.
