Abstract

The invention discloses a Mg-based 3 TeO 6 The purple inorganic pigment of structure and its preparation method and application, the molecular formula of described purple inorganic pigment is Mg 3‑2x mn x Li x TeO 6 , wherein 0.02≤x≤0.15; the preparation method of the purple inorganic pigment comprises the following steps: proportioning a compound containing magnesium, a compound containing tellurium, a compound containing manganese, Li 2 CO 3 After mixing and grinding, it is calcined at 750-900°C, and the purple inorganic pigment is obtained after cooling. The purple inorganic pigment of the invention is resistant to acid, alkali and high temperature, the preparation method is environment-friendly, and the raw materials are cheap and non-toxic, and can be used in the chemical production of paints, coatings, paintings, plastics and rubber.

Description

technical field [0001] The present invention relates to the field of preparation of inorganic pigments, more specifically, to a Mg-based 3 TeO 6 Structured purple inorganic pigments and their preparation methods and applications. Background technique [0002] Inorganic pigments are widely used in construction materials, paints, plastics, inks, military camouflage and other industries because of their stable properties, bright colors, and complete and pure color spectrum. However, existing commercial inorganic pigments still have various problems. First, the commercial pigment chrome yellow (PbCrO 3 ), cadmium yellow (CdS), antimony yellow (Sb 2 o 3 2PbO) and molybdenum red [Pb(Cr,Mo,S)O 4 ] and other toxic heavy metal elements such as lead, chromium, cadmium, etc., will endanger human health and pollute the environment, and its application fields are also subject to more and more restrictions. Second, the pigment production process is complex and produces toxic by-pro...
