Bauxite homogenizing material as Sialon raw material and production method of bauxite homogenizing material
The invention relates to a bauxite homogenizing material as a Sialon raw material and a production method of the bauxite homogenizing material, and belongs to the technical field of production of refractory materials. The homogenizing material is prepared by adding excessive metal aluminum powder to reduce SiO2, Fe2O3 and TiO2 in aluminum bauxite and coal gangue. The bauxite homogenizing material comprises active ingredients Al2O3, Si and Al and a small amount of Fe and Ti, wherein the amount of Al2O3 is 85 to 90wt%, the total amount of elemental Si and elemental Al is 8 to 12wt%, the weight ratio of elemental Si to elemental Al is (3-4): 1, and the bauxite homogenizing material is a very good raw material for synthesizing a Sialon material. When a refractory brick made from the homogenizing material is fired by nitriding, Sialon is formed in the matrix of the brick, and homogeneous Sialon can also be formed inside particles; and meanwhile, the homogenizing material is also a very good raw material for producing an iron runner material and a refractory brick with high refractoriness under load and low creep.
