zeoliitit
Zeoliitit, or zeolites, are a family of hydrated aluminosilicate minerals and synthetic crystalline materials known for their three-dimensional framework of SiO4 and AlO4 tetrahedra. The framework carries a negative charge that is balanced by exchangeable cations such as sodium, potassium, or calcium. This arrangement creates uniform, rigid pore systems with molecular-sized channels, giving zeolites distinctive adsorption, ion-exchange, and catalytic properties that resemble molecular sieves.
Natural zeolites form in volcanic rocks and sedimentary environments through the alteration of aluminosilicate materials in
Zeolites are classified by their framework types, such as FAU (faujasite; includes zeolite Y), LTA (zeolite A),
Safety and handling vary by form. Synthetic zeolites are generally considered low in toxicity, while certain
