Zeolite raw material liquid, the zeolite crystals creating method creates a zeolite raw material liquid, and zeolite membrane

PROBLEM TO BE SOLVED: To achieve sufficient strength of a zeolite thin film even when a zeolite crystal other than MFI type is a main component, and to realize reduction of dielectric constant, improvement of surface flatness, and improvement of hydrophobicity, Cost reduction is also possible by simplifying the production process. SOLUTION: A method for producing a raw material liquid for zeolite according to the present invention comprises aging a synthesis solution composed of TEOS, TBAOH, water, and alcohol, followed by hydrothermal synthesis treatment at a predetermined temperature to form MEL-type zeolite nanocrystals. The zeolite crystal solution containing the MEL-type zeolite nanocrystal is mixed with at least one organic solvent such as an alcohol-based organic solvent, an amide-based organic solvent, or a ketone-based organic solvent, or two or more mixed organic solvents. A raw material liquid for zeolite is prepared. [Selection] Figure 1
