Temperature notice:
The maximum temperature depends on the alumina grade, crucible
dimensions, heating rate, holding time, furnace atmosphere and
actual working conditions. The 1800°C value applies only to
short-term exposure and should not be treated as the recommended
continuous operating temperature.
