MAGNESIUM HYDROXIDE SOLID SOLN PRODN-BY ADDING AN AQ SOLN CONTG METAL SALT E.G. IRON TO AQ DISPERSION COMPRISING MAGNESIUM HYDROXIDE

摘要

The present invention relates to a magnesium hydroxide solid solution, a method for producing the same, and a use thereof, wherein the magnesium hydroxide solid solution contains a small amount of divalent metal ions having a performance comparable to that of a magnesium hydroxide solid solution having a uniform solution of divalent metal ions. To use, the following formula (1);Wherein M ²⁺ represents at least one divalent metal ion selected from the group consisting of Mn ²⁺ , Fe ²⁺ , Co ²⁺ , Ni ²⁺ , Cu ^2+, and Zn ²⁺ , and x is 0.001 ≦ x0 Magnesium hydroxide solid solution in which M ²⁺ is undistributedly employed in a high concentration near the surface of each crystal, a flame retardant containing the solid solution as an active ingredient, A flame retardant resin and / or a rubber composition containing the flame retardant and the solid solution are prepared.
