A Method for Synthesis Zeolite and Amorphous Materialize of Natural Layered Mineral using Mechanochemical Treatment

摘要

PURPOSE: Provided are methods for synthesizing amorphous material and zeolite from layered minerals at low temperature and atmospheric pressure by breaking crystal structure of layered minerals by mechanochemical treatment to provide activity to the minerals. CONSTITUTION: The method comprises the steps of (a) introducing 6.5g of layered minerals into a planetary mill with 500cc of mill capacity, (b) introducing 5 to 9 balls with a diameter of 10 mm into the mill, and (c) crushing dried layered minerals at 500 to 800 rpm for about 1 hour, wherein the layered mineral is mica, vermiculite, monmoliolite, serpentine, or caolilite. The method comprises the steps of (a) introducing 6.5g of layered minerals into a planetary mill with 500cc of mill capacity, (b) introducing 5 to 9 balls with a diameter of 10 mm into the mill, (c) crushing dried layered minerals at 500 to 800 rpm for about 1 hour, thereby obtaining amorphous material wherein the layered mineral is mica, vermiculite, monmoliolite, serpentine, or caolilite, (d) causing a reaction between the amorphous material powder prepared from layered minerals and alkali aqueous solution with 2.5 moles in a water bath at 50 to 70 C for 12 hours, thereby obtaining slurry, and (e) filtering and drying the slurry, thereby obtaining zeolite.
