Abstract: |
The mullite ceramic support was prepared by a pressing method using capacitor mullite powder as a starting material, coal fly ash as sintering additive and activated.The effectsof sintering temperature on phase composition, microstructure and chemical resistance of the samples were systematically studied. The results show that the best support with mullite of 85 wt% , coal fly ash of 15 wt% sintered at 1350℃has a porosity of 37.15%, a mean pore size of 2.31 μm,a flexural strength of 59.85 MPa, a water flux of 14.5 m3·m-2 ·h-1 ·MPa-1. The flexural strength decreases from 59.85 to 55.65 MPa and 47.72 MPa when the support immerses in 15% HCl and 15% NaOH for 40 h respectively. The support hasgood chemical corrosion resistance. |
