Abstract (en)

[origin: WO03076523A1] The invention relates to the use of precipitated silica having a DOP oil absorption of at least 260 ml/100g as a raw material in order to produce a colorant by impregnating said silica with an inorganic pigment in the form of a soluble salt and, in particular, with an inorganic pigment based on soluble iron sulphate. The invention also relates to a colorant that can be produced by calcinating and, optionally, grinding a precipitated silica with a DOP oil absorption of at least 260 ml/100g which has already been impregnated using an inorganic pigment in the form of a soluble salt, such as a soluble iron sulphate-based inorganic pigment. The colorant thus obtained can be used to dye ceramic materials, such as ceramic tiles, and bituminous or hydraulic binding materials.
