| description | EL PRESENTE INVENTO SE REFIERE A UN PROCEDIMIENTO PARA LA PREPARACION DE PIGMENTOS AMARILLOS A BASE DE OXIDO DE HIERRO, CON UN BAJO EFECTO SILKING, POR EL CUAL SE PROCEDE A LA FORMACION DE NUCLEOS DE PIGMENTOS AMARILLOS DE (ALFA)-FEOOH, EN PRESENCIA DE COMBINACIONES DE LOS ELEMENTOS B, AL, GA, SI, GE, SN O PB, EN CANTIDADES DESDE 0,05 A 10 % EN PESO, CALCULADOS COMO OXIDOS DE VALENCIA 3 O 4, Y REFERIDOS AL (ALFA)-FEOOH PRECIPITADO AL PREPARAR LOS NUCLEOS, Y DEJANDO QUE SOBRE ESTE NUCLEO AMARILLO CREZCA UN PIGMENTO DE OXIDO DE HIERRO.
The present invention relates to a process for preparing iron oxide yellow pigments having a low silking effect, the formation of nuclei of needle-shaped alpha -FeOOH yellow pigments being performed in the presence of compounds of the elements B, Al, Ga, Si, Ge, Sn or Pb in amounts from 0.05 to 10% by weight, calculated as the tri- or tetravalent oxides, and relative to the alpha -FeOOH precipitated in the formation of nuclei, and an iron oxide yellow pigment being allowed to grow on the yellow nucleus. |
