Abstract

The present invention relates to a layered double hydroxide variant sepiolite compound and to a method for preparing same. In detail, the present invention relates to a layered double hydroxide variant sepiolite compound and to a method for preparing same wherein a thermal transformation process and a hydration process are performed on layered metal hydroxide which is an anionic compound, so that the layered double hydroxide variant sepiolite compound has a channel structure in which blocks and tunnels intersect each other in a crystallographic axis, and has physicochemical stability, a wide specific surface area, and porosity, and thus improved thermal properties. The sepiolite compound according to the present invention can be applied to a variety of fields including the production of thermal stabilizers, flame retardants, absorbents, filters, spandex, fillers, catalysts, decolorants, etc.
