Abstract

The invention discloses a preparation method of titanium-rich aluminum titanate carriers. The preparation method comprises the following steps of 1, preparing coated titanium sol liquid and nanometertitanium dioxide turbid liquid; 2, putting aluminum sol into a reaction kettle; then, sequentially adding the nanometer titanium dioxide turbid liquid and ethyl silicate to obtain mixed liquid; performing reduced pressure distillation reaction on the mixing liquid to obtain thick liquid; 3, preparing a porous coarse mold; 4, preparing a film plating coarse mold; 5, performing gradient sintering onthe film plating coarse mold to obtain the porous titanium-rich aluminum titanate. Compared with a conventional carrier film plating method, the preparation method has the advantages that the methodrealizing the titanium element and carrier connection preferable treatment is provided; the steps are simple; the process can be easily realized; a gradient sintering method is used; the obtained aluminum titanate has high titanium content; air pores are uniform; the intensity is improved; good use values are realized.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of aluminum titanate carriers, and in particular relates to a preparation method of titanate-rich aluminum titanate carriers. Background technique [0002] With the rapid development of modern metal smelting, aerospace and automobile industries, the performance requirements of ceramic materials are constantly increasing, especially in terms of high temperature resistance and thermal shock resistance. Aluminum titanate (Al 2 TiO 5 ) The material has a high melting point, good impact resistance and thermal shock resistance, these advantages make it have great application potential under the conditions of higher temperature and frequent cold and heat exchange. In addition, aluminum titanate materials also have the advantages of low expansion, fire resistance, corrosion resistance, and alkali resistance, so aluminum titanate materials are also widely used in refractory bricks and chemica...
