Precautions For The Use Of Alumina crucible
Various Laboratory Metal Analysis
Shuttle Kiln Burning Pigment
● Preheating and cooling :
Before using the alumina cruciblemust be preheated to prevent the damage of the crucible cauby rapid temperature change. Similarly, a slow cooling proce!also required after use to prevent the sudden loss of heat frorcausing damage to the crucible.
● Avoid collision :
Alumina crucible is relatively fragile, avoid cwith hard objects, in order to prevent breakage affecting theexperiment.
● Cleaning method :
Clean it after use to avoid residue affectinext experiment.
