Embodiment Construction

[0010] 1. Analysis of chemical composition of red mud

[0011] Raw materials: red mud (solid waste directly discharged from an aluminum factory in Shanshan).

[0012] After the red mud was air-dried, its chemical composition was determined by a multi-element rapid analyzer, and the results are shown in Table 1.

[0013] Table 1 Analysis results of chemical composition of red mud

[0014]

[0015] Chemical composition analysis shows that the red mud sample contains up to 29.84% of ferric oxide and up to 20.96% of alumina, which can be used to prepare ceramic pigments.

[0016] 2. Brown ceramic pigment formula with red mud as raw material

[0017] The above red mud sample is used as raw material, after removing water, carbon dioxide and volatile substances, it is mixed with other chemical raw materials, calcined at high temperature, cooled and crushed to obtain the best chemical formula of brown ceramic pigment with good quality, the formula See Table 2.

Abstract

The invention relates to a method for preparing a brown ceramic pigment from red mud, and belongs to the technical field of inorganic chemical industry. On the basis of analyzing the chemical components of the red mud, the optimal formula of the brown ceramic pigment prepared from the red mud is developed, and the brown ceramic pigment is prepared by uniformly ball-milling the red mud and other chemical raw materials according to the formula, calcining at high temperature, cooling and grinding. A glaze spraying test proves that the prepared brown ceramic pigment has a good color development effect, and the production cost of the ceramic pigment can be greatly reduced, so the method can be used for preparing and producing the ceramic pigment.

Description

technical field [0001] The invention relates to a method for preparing a brown ceramic pigment using red mud as a raw material, and belongs to the technical field of inorganic chemicals. Background technique [0002] Ceramic pigment is an indispensable and extremely important decorative material for ceramic products. With the improvement of people's quality of life and the beautification of the living environment, building sanitary ceramic products have entered thousands of households. Therefore, the stability of ceramic pigments and the diversity of hues have become the goals pursued by ceramic pigment factories. In particular, with the emphasis on the recycling and reuse of waste resources, research and development of high-quality ceramic colorants using cheap waste resources as raw materials to reduce production costs has become the focus of research and development for ceramic colorant manufacturers. [0003] Red mud is reddish-brown powdery mud-like strongly alkaline ...
