It contains little hexagonal plate-shaped magnesium hydroxide, which provides a beneficial fibrous composite metal hydroxide as a reinforcing material for resins and rubbers. The crystal water discharge temperature can be set at a point between the crystal water discharge temperature of aluminum hydroxide and the crystal water discharge temperature of magnesium hydroxide.n n n This fibrous composite metal hydroxide is excellent in flame resistance and acid resistance. This fibrous composite metal hydroxide has a length / diameter ratio of about 10 or more, an average diameter of about 0.1-10 mu m and an average length of about 2 to 1000 mu m, and has the following formula (1).n n n M 2+ x Mg1-x (OH) 2 .... (1)n n n Wherein M is at least one member selected from Mn, Fe, Co, Ni, Cu and Zn, and x is in the range 0.005 x 0.5. |
