2020-10-15 The grinding synthesis method (GSM) is an appropriate approach towards creation of an intra-crystalline mesoporous ZSM-5 zeolite without using any mesoporous templates and pre-/post-treatments. The formation of the mesoporous zeolite structure is attributed to the imbalance between the crystallization and dissolution rates, and is mainly controlled by the alkalinity of the precursor gel.

1990-6-1 Abstract. The hydrothermal treatment in NaOH solution of clays activated by grinding leads to the formation of different zeolites, whose nature depends on the amorphization of the clay obtained by applying a periodic stress by means of an oscillating mill. In this way, hydroxysodalite, mixtures of hydroxysodalite and NaA zeolite, or NaA pure ...

2018-2-22 Zeolites are crystalline aluminosilicates of the alkaline and alkaline-earth metals. They possess many desirable ion- exchange, molecular sieving, and catalytic properties, which make them valuable mineral commodities. Synthetic zeolites have been used for over 25 yr in commercial processes, but only recently have natural zeolites been viewed as potentially valuable mineral commodities.

As important industrial materials, microporous zeolites are necessarily synthesized in the presence of solvents such as in hydrothermal, solvothermal, and ionothermal routes. We demonstrate here a simple and generalized solvent-free route for synthesizing various types of zeolites by mixing, grinding, and heating solid raw materials.

2019-4-12 Zeolites were first recognized as a new group of minerals by Cronstedt with the discovery of stilbite in 1756. The word zeolite was coined from the two Greek words meaning “to boil” and “a stone” because of the loss of water when heated in the mineralogist’s blow pipe.
