Continuous process and apparatus for preparing inorganic materials employing microwave

Abstract

This invention relates to a continuous microwave synthesis process of inorganic materials and its apparatus and more particularly, to the process of synthesizing inorganic materials prepared in a manner such that after preparing a mixed solution of precursor materials for various inorganic materials such as porous molecular sieve, layered compounds and ceramics, this mixed solution is continuously added to a tube-type microwave reactor using a slurry pump for the synthesis and crystallization of inorganic materials. Thus the manufacturing process of this invention has the following advantages: (1) the reaction time is further shortened by several to tens of minutes for crystallization, compared to the conventional hydrothermal reaction requiring a prolonged time, (2) the continuous manufacturing and collection processes of this invention can give access to mass-scale production of inorganic materials with relatively small facility, compared to the conventional batch hydrothermal or microwave synthesis, and (3) less amount of organic templating agent can be required during the manufacture of porous molecular sieve.
