As early as 200 years ago, B.
This structure makes the zeolite crystals have pores with a certain pore size
[Chemical formula]
The general chemical formula of zeolite is: A m B p O 2p ·nH 2 O, and the structural formula is A (x/q) [(AlO 2 ) x (SiO 2 ) y ] n (H 2 O), where: A is Ca, Cations such as Na, K, Ba, Sr, B is Al and Si, p is the valence of the cation, m is the number of cations, n is the number of water molecules, x is the number of Al atoms, y is the number of Si atoms, (y/x) usually From 1 to 5, (x+y) is the number of tetrahedrons in the unit cell
[Physical and chemical properties] Zeolite can be divided into two categories: natural zeolite and artificial zeolite
Non-toxic, harmless, wear-resistant, corrosion-resistant, good thermal stability, cheap and easy to obtain
