  • Publication number: 20110213065
    Abstract: Quite unexpectedly, by suitably modifying the crystal structure of hydrogarnets of the general formula MII3MrI-III2(OH)12 (where MII denotes divalent metal ions, especially alkaline earth metal ions, of Group IIA of the periodic table and MIII denotes trivalent metal ions of Group IIIA of the periodic table, especially aluminum) with suitable amounts of incorporated silicate and/or phosphate, flame retardants having both a higher flame retardant efficiency than such traditional mineral flame retardants as ATH and MDH, and a higher thermal stability than ATH can be produced. It has also been found that synthetic hydrogarnets of the general formula MII3MrIII2(OH)12(where MII and MIII are as defined above) having cubic crystal and these synthetic hydrogarnets also show high flame retardant efficiency.
