| titleOfInvention | Preparation of red iron oxide pigments |
| abstract | Process for the preparation of hematite pigments, comprising at least the reaction of at least iron with an aqueous suspension of hematite germ, containing hematite germs having a particle size of 100 nm or less and a specific BET surface of 40 m2 / g to 150 m2 / g (measured according to DIN 66131), and a solution of iron nitrate (ll), in the presence of at least one oxygen-containing gas at temperatures of 70 to 99 ºC, generating a suspension of hematite pigment, characterized in that the hematite germ suspension is added to at least the iron, and before the addition, after the addition or simultaneously to the addition of the hematite germ suspension the iron nitrate solution is added (ll) to the mixture of at least the hematite and iron germ suspension so that from 80% to 100% of the entire reaction time the concentration of iron nitrate (ll) amounts to 0.1 to 25 g / I liquid phase First, preferably at 1 to 20 g / l of liquid phase, calculated with respect to Fe (NO3) 2 free of water. |
