Abstract
Carbonyl iron powder (CIP) can be protected from extensive atmospheric oxidation by mixing and heating it with a silicon compound having one or more reactive groups. The resulting CIP is more readily accepted by a silicone binder when preparing mixtures thereof.
Claims9
A method for preparing a composition containing carbonyl iron powder and a silicone binder, said method comprising heating and mixing the carbonyl iron powder with an amount of a silicon compound which contains one or more reactive silicon-bonded radicals, said amount being sufficient to reduce the atmospheric oxidation of the carbonyl iron powder, and then mixing the resulting carbonyl iron powder with the binder.
