Hydrotalcite particles, method for producing hydrotalcite particles, resin stabilizer containing hydrotalcite particles, and resin composition containing hydrotalcite particles

Hydrotalcite particles having a ratio of an intensity to a half value width, intensity/half value width, of higher than or equal to 4000 cps/degree, the intensity and the half value width being values of a diffraction peak of crystal plane (015) in an X-ray diffraction pattern, wherein the hydrotalcite particles are produced by a method comprising:

• dissolving aluminum hydroxide in an alkaline solution to prepare an aluminate solution;
• causing a reaction of the aluminate solution with carbon dioxide to precipitate a low-crystallinity aluminum compound;
• causing a first-order reaction by mixing the low-crystallinity aluminum compound with a magnesium compound to prepare a reactant containing hydrotalcite nuclear particles;
• and
• causing a hydrothermal reaction of the reactant to synthesize hydrotalcite particles.
