Completely filled crucible with ionic liquid (10ml) treated with
high temperature (1000oC) causes sample surface to solidify. Water of
crystallization starts to boil inside the crucible leads to sudden pressure
explosion for the sample. The opened side valves protected the quartz
tube from breakage Figure 6.
Assuming that furnace valves were closed in case of vacuum or
under certain gases, serious hazard will occur due to glass breakage.
Lesson Learned
In case of such salts (ionic liquids) thermal treatment, sample
preparation must be done in appropriate amount to ensure uniform
heat distribution to all parts of the sample which prevents drying some
parts without the other as stated in the case provided.
A successful experiment was done keeping in mind the lessons
derived from past experience
