Zeolite is an aqueous alkali metal or alkaline earth metal aluminosilicate mineral. Zeolite has the properties of adsorption, ion exchange, catalysis, acid resistance and heat resistance, so it is widely used as adsorbent, ion exchanger and catalyst, as well as gas drying, purification and sewage treatment. Zeolite also has "nutritional" value. Due to the porous silicate nature of zeolite, there is a certain amount of air in the pores, which is often used to prevent explosion and boiling. During heating, the air in the small hole escapes, playing the role of gasification core, and small bubbles are easy to form on its corners.
