Formation mechanism of microwave synthesized LTA zeolite membranes

Zeolitic Imidazolate Frameworks (ZIF): A Potential Membrane for CO2/CH4Separation

“…The high quality of the ZIF membrane can be obtained within a short synthesis duration. Li et al (110) reported that the defects found in the LTA zeolite membrane prepared by MW heating decreased significantly when compared to LTA membranes synthesized by a conventional heating Downloaded by [University of Texas Libraries] at 04:58 04 December 2014 method. Characteristics of MW with a fastened crystallization process (39,109) suppressed the maturation-nucleation process or Ostwald ripening process compared to conventional heating.…”

Synergistic Effect of 4A Zeolite from Rice Husk Ash without Aging Time and Silane on the Adhesion Properties of a Warm Mix Asphalt

“…46 Nevertheless, the effects of the microwave irradiation on the chemical reactions have not been fully understood and remain controversial. 46,48 The use of microwave-assisted hydrothermal synthesis to obtain LTA zeolite has been reported several times 27,30,44,45,47,[49][50][51][52][53][54][55] using different procedures and conditions. The synthesis is usually developed from a gel originated from a sodium aluminate and a sodium silicate solution requiring long and vigorous stirring to be homogenized.…”

Hydrothermal and microwave synthesis of SAPO (CHA) zeolites on aluminium foams for heat pumping applications

“…Microwave synthesis of SAPO zeolites, indeed, is a well-established method as proved by numerous research papers reporting the successful preparation of various SAPO types [17][18][19][20]. However, few papers are available in literature concerning microwave synthesis of zeolites on supports [21][22][23], e.g. the synthesis of SAPO-34 membranes by microwaves was only recently reported by Chew et al [24].…”
