Novel corrosion-resistant ceramic material and preparation method thereof
The invention discloses a preparation method of a novel corrosion-resistant ceramic material. The preparation method comprises the following steps: firstly, respectively grinding 15-35 parts of silicon dioxide, 4-8 parts of magnesium titanate, 2-7 parts of calcium oxide and 8-13 parts of calcium borate to 100-200 meshes, and adding the grinded materials into a reactor for mixing; grinding 12-14 parts of barium nitrate and 5-8 parts of potassium silicate to 50-80 meshes, and adding the grinded materials into the reactor for stirring reaction at the temperature of 30-40 DEG C; respectively grinding 5-11 parts of aluminium hexafluorosilicate, 6-14 parts of aluminum barium magnesium oxide, 2-6 parts of barium azide and 8-13 parts of barium laurate to 60-80 meshes, and continuously adding the grinded materials for stirring reaction, so as to obtain mixed powder A; performing extrusion molding on the mixed powder A by a twin-screw extrusion machine, then, placing the mixed powder subjected to extrusion molding into a muffle furnace, performing sintering treatment, and cooling, so as to obtain the corrosion-resistant ceramic material. According to the invention, overall improvement on the corrosion resistance of the original ceramic material is achieved, the swelling ratio of the ceramic material processed through H2SO4 with the concentration of 50% is 0.31-0.64%, and the swelling ratio of the ceramic material processed through an NaOH solution with the concentration of 50% is 0.21-0.58%.
