چکیده انگلیسی


• Analcime is synthesized for the first time using quartz syenite by alkali-hydrothermal method.
• Quartz syenite is the starting material for synthesis of analcime and leaching of potassium.
• The isometric trapezohedral analcime ranges in uniform particle size from 15 to 20 μm.
• Conversion mechanism is attributed to dissolution–precipitation process.

Analcime was successfully synthesized for the first time via a hydrothermal treatment of quartz syenite powder and NaOH solution. The experiments were carried out at the temperature from 240 °C to 260 °C for 2–8 h using different concentrations of NaOH solution and mass ratio of NaOH/syenite. The as-prepared samples were characterized by X-ray fluorescence, X-ray powder diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. The results indicate that the crystalline analcime can be prepared using natural quartz syenite as an economic raw material.
