Abstract

PURPOSE: To manufacture an iron oxide pigment having a uniform grain size by blowing air into a colloidal suspension of ferrous carbonate to cause oxidation and dehydrating the resulting ferric hydroxide.
CONSTITUTION: An aqueous soln. of sodium carbonate is poured in a reactor, and a soln. of ferrous sulfate is slowly added and agitated to prepare a suspension of ferrous carbonate. A nonoxidizing gas such as nitrogen is blown into the suspension and agitated for 2W4hr to prepare a fine colloidal soln. While adjusting the soln. to 7W10pH, a gas contg. oxygen such as air is blown to precipitate yellow ferric oxide hydrate. This precipitate is separated by filtration, washed, dried at 100°C, and dehydrated by heating to 250W500°C to obtain a red iron oxide pigment having a uniform grain size.
