Calcium hexaluminate based pouring material not polluting high-purity aluminum solution

The invention discloses a calcium hexaluminate based lining pouring material not polluting components of high-purity aluminum although contacting with a high-purity solution in the refinement, fusion and insulation processes of the high-purity aluminum. Raw materials for preparing the pouring material comprise the following components: a synthesized calcium hexaluminate material, an ancillary material, micropowder, cement and an additive. By using the pouring material, a defect that the existing non-stick aluminum material has a certain aluminum corrosion resisting effect on the ordinary alloy but can not meet the high-purity requirement of the high-purity aluminum for the influence and pollution of components in an aluminum solution is overcome so as to solve the pollution problem of brasque material on the high-purity aluminum solution.
