摘要：
A cyclophosphazene fluid composition containing organometallic or inorganic metal salts as antioxidants the antioxidants for use therein, and a method therefor, are disclosed herein. Suitable organometallic salts are formed by reacting a metal hydroxide with benzoic acid, substituted benzoic acids, or substituted phenols. The preferred inorganic metal salts effective for this purpose include various metal borates. The metal salt antioxidants are effective for reducing oxidation in the cyclophosphazene fluid in amounts of less than about 1% by weight of the overall composition.
