[0004] (1) Phase-separated glazes often need to be laid out twice, first with a layer of base material, and then with a layer of phase-separated raw materials, using the difference in viscosity of the two glazes at high temperature to make the crystal phase from the phase separation produce a kiln effect , if only one layer of material can be used to realize the production method of phase separation kiln transformation effect, the production efficiency can be greatly improved. ZL201210094756.8 discloses a production method using spodumene, quartz, calcite, talc, aluminum oxide, zinc oxide, , zircon powder, ashes, lithium carbonate and boric acid and other raw materials to prepare the basic crystal glaze, a

Abstract
The invention belongs to the technical field of building ceramic production, and particularly relates to a method for producing split-phase furnace transmutation decorative composite materials from red mud by roller kilns. The method includes placing raw materials, which include the red mud, feldspar, vanadium and titanium slag, quartz, borax, lepidolite and talc, in frit furnaces, melting the rawmaterials at the temperatures of 1400-1500 DEG C, then carrying out water quenching and crushing, carrying out sieving to obtain sieve residues and mixing the sieve residues with one another to obtain split-phase furnace transmutation raw materials; placing raw materials, which include feldspar, clay, flint clay, pyrophyllite and aragonite, in ball mills, carrying out ball milling for 36 h, thencarrying out spray granulation, placing granules in dies and carrying out compression molding to obtain green bodies; arranging the obtained split-phase furnace transmutation raw materials on the green bodies and drying and firing the green bodies with the split-phase furnace transmutation raw materials by the roller kilns to obtain the split-phase furnace transmutation decorative composite materials. The method has the advantages that all the requirements on the usability and the decorativeness of the traditional ceramic can be met by the split-phase furnace transmutation decorative compositematerials produced by the aid of the method, glaze coloring materials are omitted in production procedures, and accordingly the method is a green and environment-friendly production process.
Description
technical field [0001] The invention belongs to the technical field of building ceramic production, and in particular relates to a method for producing phase-separated kiln-transformed decorative composite materials by using red mud through a roller kiln. Background technique [0002] In recent years, with the continuous improvement of the industrial level, the number of industrial products in China has increased significantly, so the discharge of industrial solid waste is very large. Among them, red mud, as an industrial by-product of alumina, has an annual discharge of more than several million tons , the annual discharge of vanadium-titanium slag is more than 20 million tons. The technology of developing and utilizing these solid wastes is also constantly developing, but they are mainly focused on using them as low value-added directions such as roadbed filling materials. However, when red mud is used as a raw material for ceramic matrix composites, its color, viscosity ...
