Abstract

From Kaolin (Lam Dong) with major components: SiO2 (43%), Al2O3 (34%) and the others preparation of priliininarypills is made with Bentonite (5-20% mass weight). After transfer to metakaolin, gelation anh crystallizing mixture in base medium, the pellet of Zeolite NaA is got. From the research result we can see: Transference of solid metakaolin directly to crystall forin happens in the proper base medium. Zeolite NaA with over 20% water absorption can be used in absorption and adsorption processes.
