Abstract： |
| The influence of the support sintering temperature is studied in the paper by adding copper oxide sintering aids, DSC、XRD、SEM,、The point bending method and self-made device are used to research phase composition、microstructure、rupture strength、pure water flux and porosity. Results show: the support produce CuAl2O4,which can enhance mechanical strength of aluminum oxide ceramics (55.82MPa) when sintering temperature rise to 1100℃; quality loss is 1.82% and 0.68%,respectively in the 10% volume fraction HCl and in the 1mol/L NaOH. |
