Figure 2.5. Three different zeolites (Byrappa and Yoshimura, 2001)2.3 PropertiesMineral species such as zeolite has unique properties which are dependentupon its crystal structures and thus the type of inner cavities such as the pores, theirsize and form. Many of these properties are especially desirable for environmentalprotection, such as cation exchange capacity, adsorption properties, acid stability,ammonium capacity and wet attrition resistance. In Table 2.2, we can see amicroporous solid with a broad range of physico-chemical properties of zeolites andrelated materials, such as phosphate-based molecular sieves. Table 2.3 briefly thedescription of each type of common zeolites properties.15
