Abstract

PURPOSE: To prepare α-hydroxy iron hydroxide shaped like a sindle with a uniform grain distribution with addition of a solution of ferric salt to an alkaline solution mainly composed of carbonate.
CONSTITUTION: One, two or more kinds of ferric salt including ferric sulfate, ferric chlorate and derric nitrate are added slowly to an alkaline solution mainly composed of carbonate including sodium carbonate, potassium carbonate and ammonium carbonate, which may be combined with a small amount of NaOH, KOH or the like as required, with agitation. With the addition of such substances. CO2 is generated raising the temperature of the liquid. To check the rise in the temperature porperly, the velocity of the addition is adjusted. The reaction is normally complted with the end of the addition. In the case of combining caustic soda, the mixture requires aging below 80°C for a given time after the addition.
