Advantages of alumina ceramic crucible:
(1) Easy to wash and keep clean.The glaze of ceramic crucible is bright and delicate, and it is easy to wash after being stained.
(2) Porcelain pores are very few, water absorption is very low.The solution stored in ceramic crucible and sealed tightly can prevent the solution from volatilization, penetration and the invasion of external bacteria.
(3) stable chemical properties, durable.This point is better than metal products such as copper, iron, aluminum, etc., ceramic crucible has a certain acid, alkali, salt and the ability of atmospheric carbonate gas erosion, not easy to react with these substances, not rust aging.
(4) good thermal stability, slow heat transfer.Ceramic crucible has the performance of not easy to burst when undergoing the change of sudden heat and sudden cooling of certain temperature difference, this point it is superior to glassware, it is a bad conductor of heat, heat transfer is slow, used to hold boiling water or boiling hot solution, when the end is not too hot.
