Abstract: The invention relates to the production of mixed-metal-oxide inorganic pigments, using industrial waste as raw materials, comprising the following steps: (i) characterization and selection of wastes; (ii) their treatment, if required; (iii) formulation + dosing + mixing of components; (iv) drying + calcination; and (v) washing + milling. Selected wastes might be used in the as- received condition or after drying or calcination. The present invention deals with materials that are produced by colorants or pigments producers mainly for use in the ceramic sector, since formulations are stable at high temperatures and act as colorants of glazes or ceramic bodies. The use of high temperatures might also assure the desirable inertization of possible hazardous species.

Abstract translation: 本发明涉及使用工业废物作为原料的混合金属氧化物无机颜料的制备，其包括以下步骤：（i）废物的表征和选择; （ii）如果需要，他们的待遇; （iii）制剂+配料+组分混合; （iv）干燥+煅烧; 和（v）洗涤+研磨。 所选择的废物可以在接收到的条件下或干燥或煅烧后使用。 本发明涉及由着色剂或颜料生产者生产的材料，主要用于陶瓷领域，因为制剂在高温下是稳定的并且作为釉料或陶瓷体的着色剂。 使用高温还可以确保可能的危险物质的理想惰性化。
