Abstract
The invention discloses a preparation process of an orange-yellow high temperature-resistant magnesium ferrite pigment, which comprises the following steps of: mixing a certain amount of iron oxide yellow filter cakes with industrial activity magnesium oxide and simultaneously adding an assistant playing dispersion and anti-sintering roles to carry out batching, pulping, high-speed dispersion, suction filtration, drying, roasting reaction and crushing to obtain the orange-yellow high temperature-resistant magnesium ferrite pigment. The preparation process has the advantage that the needle iron yellow fresh filter cakes with good reaction activity and grain sizes controlled within a certain range and a certain specification of active magnesium oxides produced by the company are preferably selected to be pulped and mixed by a wet process. The invention has the beneficial effects that the production process flow can be greatly simplified; the preparation process is easy in operation, high in yield and low in cost; and the prepared product is pure in color and is good in dispersibility.
