Abstract

The invention discloses a purple inorganic pigment based on a Mg3TeO6 structure as well as a preparation method and application thereof, the molecular formula of the purple inorganic pigment is Mg<3-2x>MnxLixTeO6, and x is more than or equal to 0.02 and less than or equal to 0.15; and the preparation method of the purple inorganic pigment comprises the following steps: mixing and grinding a magnesium-containing compound, a tellurium-containing compound, a manganese-containing compound and Li2CO3 in proportion, calcining at 750-900 DEG C, and cooling to obtain the purple inorganic pigment. The purple inorganic pigment is resistant to acid, alkali and high temperature, the preparation method is environmentally friendly, the raw materials are cheap and non-toxic, and the purple inorganic pigment can be applied to chemical production of paint, 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...
