Method for manufacturing maghemite and maghemite manufactured thereby

摘要

It is an object of the present invention to provide an efficient method for producing maghemite and maghemite produced thereby. To this end, the present invention provides a method for producing maghemite comprising the steps of microwave treatment and heat treatment of FeC 2 O 4 ·2H 2 O powder in a microwave heat treatment furnace, maghemite produced thereby, and lithium-sulfur comprising the same Provided are an electrode material for a secondary battery, and a drug delivery material comprising the same. According to the present invention, in the process of manufacturing maghemite, there is no need for a separate pretreatment step for raw materials, and it is possible to manufacture maghemite in a short time at a low temperature compared to the conventional heat treatment process, thereby greatly improving the process efficiency. can be improved, and thus, there is an effect of greatly improving the ease of application of the maghemite produced in the field of application.
