XTL sintyron 99 alumina refractory ceramic crucible sagger

Alumina Crucible with alumina content of more than 95% is called corundum crucible. Corundum crucible shape is generally arc, cylindrical, and pure alumina crucible arc alumina crucible, square alumina crucible, alumina corundum ark (rectangular alumina ceramic crucible), straight (cylindrical) alumina crucible and various shaped alumina ceramic crucible. The alumina crucible is suitable for using anhydrous Na2CO3 and other weakly alkaline substances as the melt sample, and is not suitable for using Na2O2, NaOH and other strongly alkaline substances and acidic substances as the melt sample (such as K2S2O7, etc.).

The characteristics of alumina crucible are high temperature resistance, no acid and alkali resistance, cold and heat resistance, chemical corrosion resistance.

Advantages of alumina ceramic crucible:

(1) Easy to clean, keep clean. The enamel of ceramic crucible is bright and delicate, and it is easy to wash after staining.

(2) Porcelain pores are very few, low water absorption, so the use of alumina ceramic crucible to store the solution, sealed tightly, can prevent the solution volatilization, penetration and the invasion of external bacteria.

(3) Stable and durable chemical properties, better than copper, iron, aluminum and other metal products. Ceramic crucible has a certain resistance to acid, alkali, salt and carbonic acid gases in the atmosphere, so it is not easy to chemically react with these substances, no rust and no aging.

(4) Good thermal stability, slow heat transfer, ceramic crucible has rapid heating and quenching changes under a certain temperature difference.
