摘要： Provided are magnesium hydroxide particles having a hexagonal crystal form and having an aspect ratio (H) which satisfies the following expression (I), (wherein H is an aspect ratio, A is an average secondary particle diameter ( mu m) of all of the particles measured by a laser diffraction scattering method and B is a specific surface area (m /g) of all of the particles measured by a BET method), a flame-retardant comprising the particles, a flame-retardant resin composition comprising 100 parts by weight of a synthetic resin and a 5 to 300 parts by weight of the magnesium hydroxide particles, and a molded article therefrom. The magnesium hydroxide particles are hexagonal single crystals, the hexagonal form thereof are not necessarily required to be regular hexagonal, and the size thereof are not necessarily constant. However, the aspect ratio thereof has a specific value in relation to the specific surface area and the average particle diameter, and the magnesium hydroxide particles have excellent properties as a flame retardant for synthetic resins.

摘要： Magnesium hydroxide particles having a hexagonal platy crystal form and an aspect ratio (H) satisfying the following relationship (I) 0.45.A.B~H~1.1.A.B, wherein H represents the aspect ratio; A represents the average secondary diameter of all the particles as determined by the laser diffraction scattering method (.mu.m); and B represents the specific surface area of all the particles as determined by the BET method (m2/g)!; a flame retardant comprising the particles; a flame-retardant resin composition comprising 100 parts by weight of a synthetic resin and 5 to 300 parts by weight of the magnesium hydroxide particles; and a molded article obtained therefrom. The magnesium hydroxide particles are composed of single-crystal particles of a hexagonal platy form. Although the hexagonal shape need not be regular and the crystals need not have the same size, the particles have a specific aspect ratio in relation to the specific surface area and the average particle diameter. They have excellent properties when used as a flame retardant for synthetic resins.
