Hot Gas Blower (Cyberstar)

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.

Temperature Calibration

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.
