An object of the present invention is to provide a magnesium hydroxide having a high aspect ratio, a method for producing the same, and a resin composition containing the same. (A) Alkali-precipitates by adding alkali to the aqueous solution of water-soluble magnesium salt and monovalent organic acid or its salt, or (B) Co-precipitates by adding aqueous alkali solution to aqueous solution of water-soluble magnesium salt, and then adds monovalent organic acid or its salt. (C) It is a manufacturing method of magnesium hydroxide which is 0.5 micrometer or more in length (width) and an aspect ratio is 10 or more, including each process of hydrothermally treating the obtained slurry at 100 degreeC or more. |
