    We often encounter the problem of how to clean the ceramic crucible in muffle furnace. Today we Zhengzhou Kejia Electric Furnace Co., Ltd. will solve this problem for you. Please check that alumina or ceramics have been formed with your material at any stage through reaction or diffusion. Any transition metal oxide or rare earth oxide composition, alumina ceramic crucible and material reaction heating. It is generally recommended to try HCl (≥ 25 wt%). If it is ineffective, then it may be worth trying hydrochloric acid + nitric acid (volume ratio 1:1; ≥ 25 wt%), with safety issues, suitable for aqua regia. We will require all of these experiments to be carried out after washing with distilled water. The dry crucible runs slowly at 110 ℃ for 10 hours and heats up to 1000 degrees for the first time. If the marking is due to the organic part of the carbon simply change your boat / crucible in the air slowly up to 1200 degrees Celsius. A slope rate of 2 degrees and a residence time of 10 minutes at 900 degrees would be good enough to eliminate solid carbon deposition in the module.
