Abstract

TiO2, MgO and CaCO3 were selected as mineralizing agents for porous alumina ceramics, which were prepared by atmospheric sintering under air atmosphere. The effects of different contents of MgO, CaCO3 and holding time on the bending strength at room temperature, sintering shrinkage rate, apparent porosity and dissolving efficiency were studied. The results show that the addition of mineralizing agents MgO and CaCO3 can decrease the shrinkage rate, bending strength at room temperature and density, and increase the apparent porosity and the dissolving efficiency. The shrinkage rate of the samples containing MgO decreases from 1.75% to 0.21% after 1 320 ℃/3 h sintering, and the apparent porosity increases from 33.49% to 36.86%. The shrinkage of the samples containing MaO decreases from 1.88% to 0.38% after 1 320 ℃/6 h sintering, and the apparent porosity increases from 32.94% to 35.46%. The shrinkage rate of the samples containing CaCO3 decreases from 0.55% to -0.50% after 1 320 ℃/3 h sintering, and the porosity increases from 35.47% to 41.26%. The shrinkage of the samples containing CaCo3 decreases from 1.16% to -0.21% after 1 320 ℃/6 h sintering, and the apparent porosity increases from 35.96% to 42.44%. When the holding time of heating treatment is extended from 3 h to 6 h, the shrinkage rate of the samples containing mineralizing agent MgO and CaCO3 increases, while the bending strength at room temperature do not change significantly. The apparent porosity of the samples containing MgO decreases and that of the sample containing CaCO3 increases. MgO and CaCO3 can significantly improve the dissolving efficiency. The quality of the samples containing only mineralizing agent TiO2 is almost unchanged after 72 h of boiling in alkaline liquid (adding cosolvent LiF), the samples containing MgO can be completely dissolved after 24 h of boiling in alkaline liquid (no cosolvent added), and the samples containing CaCO3 can be completely dissolved after 72 h of boiling in alkaline liquid (adding cosolvent).
