Microwave heating was applied to the formation of zeolite A films on copper (Cu) and stainless steel (SUS) substrates. It was confirmed that crystallization time by microwave heating was Much smaller than that by conventional heating due to the rapid dissolution of gel, nucleation and growth of zeolite crystals. It was found that the film formation was primarily influenced by surface properties of the metal substrates: a dense film of zeolite A crystals with the size of about 0.3 ~ 1.0 μm was formed on Cu substrates. However, no layer-like zeolite film was formed on the SUS substrate. Nucleation of zeolite A crystals on metal substrates was also found to be strongly affected by the heating method and pretreatment of synthesis solution.
