Abstract: A method of making a β-SiAlON is described in involves mixing nanoparticles of AlN, Al2O3, and SiO2 with particles of Si3N4 and spark plasma sintering the mixture. The sintering may be at a temperature of 1450-1600° C. or about 1500° C. The particles of Si3N4 may be nanoparticles comprising amorphous Si3N4, or 25-55 μm diameter microparticles comprising β-Si3N4.

Abstract: This invention relates a process for preparing MTT zeolites which process includes the preparation of a sol-gel from an aluminate solution, mixing a structure directing agent with the sol-gel to form a structure directing mixture, mixing a silica with the structure directing mixture to form a reaction mixture, heating the reaction mixture in a microwave reactor to form an initial zeolite, and removing the structure directing agent to form the MTT zeolite. The invention also relates to MTT zeolites produced by the process, including ZSM-23 zeolites, as well as zeolite membranes, coating and catalysts.
