    摘要： Non-silking iron oxide yellow pigments with high color density.Iron oxide yellow pigments in the .alpha.-FeOOH modification with a silking index of less than 5 were obtained in whicha) .alpha.-FeOOH seeds are produced by precipitation from an Fe(II)-containing solution with an alkaline precipitating agent in the presence of soluble aluminium salts in an amount of 3 to 9 wt. %. calculated as Al.sub.2 O.sub.3, with respect to precipitated .alpha.-FeOOH, and subsequent oxidation to .alpha.-FeOOH andb) pigment growth is performed by precipitating further iron with simultaneous oxidation, wherein the seed/time yield is less than 0.3 h.sup.-1 and the pH value is less than 3.9 over the entire period of pigment growth andc) pigment growth is terminated at a reproduction factor between 3 and 20.
