New zeolites and new uses appeared steadily through the 1960s. An explosion of new molecular sieve structures and compositions

The crystal size of synthetic zeolites is typically found in the range of 1.0– 10.0 µm while the density varies in between 2.0 to 23.0 g/cm 3. Synthetic zeolites bulk specific gravity lies in between 0.80 and 0.90 g/cm 3 (Breck, 1984). Optically, the refractive indices of synthetic zeolite are ranging between 1.47 and 1.52.

However, natural zeolites hold an advantage over other materials because they are nontoxic and ecologically acceptable and as such materials can meet the demands which are set by environment protection laws. Unlike natural zeolites, the demand for synthetic zeolites until the year 2030 is estimated to grow in areas of industrial …

Abstract. Synthetic zeolites were studied in order to investigate their ability to encapsulate and to release drugs. In particular, a zeolite X and a zeolitic product obtained from a cocrystallization of zeolite X and zeolite A were examined. These materials were characterized by chemical analyses (ICP-AES), X-ray diffraction, nitrogen ...
