Zusammenfassung:In accordance with a method for producing hydrotalcite particles, including: a first step of dissolving aluminum hydroxide in an alkaline solution to prepare an aluminate solution; a second step of causing a reaction of the aluminate solution prepared in the first step with carbon dioxide to precipitate a low-crystallinity aluminum compound; a third step of causing a first-order reaction by mixing the low-crystallinity aluminum compound precipitated in the second step with a magnesium compound to prepare a reactant containing hydrotalcite nuclear particles; and a fourth step of causing a hydrothermal reaction of the reactant prepared in the third step to synthesize hydrotalcite particles, there can be produced hydrotalcite particles which can impart excellent heat resistance, transparency, flowability, and the like, and which are useful as a resin stabilizer and the like.
