Abstract
The present invention relates to a method for producing synthetic hectorite at a low temperature and atmospheric pressure and synthetic hectorite produced by the same, and more particularly, to a method for producing synthetic hectorite and synthetic hectorite produced by the same in which: a step of forming Li—Mg precipitates is introduced and thereby ensures an improved crystallization reaction condition and synthetic hectorite having excellent properties; and composition ratios of reactants are controlled, and thus, property control is easy.
Claims14
A method for producing synthetic hectorite, the method comprising the steps of:
- 1) preparing a precursor solution mixture comprising a lithium (Li) precursor, a fluorine (F) precursor, and a magnesium (Mg) precursor;
- 2) adding a basic catalyst into the precursor solution mixture and forming Li—Mg precipitates;
- and
- 3) adding a silica (Si) precursor into the Li—Mg precipitates and performing a crystallization reaction.
