Abstract
Provided are magnesium hydroxide particles having a hexagonal crystal form and having an aspect ratio (H) which satisfies the following expression (I),0.45·1.1·  (I) 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.
