Usage Information of 99% Alumina Crucibles:
1.The crucible should be dried in an oven at a temperature of about 105°C for 120 minutes to remove moisture before first use.
2.Do not heat it directly with gasoline gun, acetylene gun or alcohol torch to prevent cracking due to uneven heating of the crucible.
3.Avoid quick heating up and cooling down. Heating temperature ≤1200 ℃,the rate of temp change should be <5 ℃ / min; Heating temperature >1200 ℃,the rate of temp change should be <4 ℃ / min.It is recommended that cool the temperature down with electricity powering on, otherwise the crucible may crack due to quick cooling down of oven if the electricity turned off.
4.The distance between the product and the heating elements (such as carbon tube, silicon molybdenum rod or heating wire, etc.) should be >2cm.
