| 摘要 |
<p>The invention relates to a porous structure containing a ceramic material mainly including or constituting a pseudo-brookite oxide material containing titanium, aluminum, magnesium, and zirconium in proportions such that the pseudo-brookite phase substantially fits the composition of: (Al2TiO5) x (MgTi2O5) y (MgTiZrO5) z, said material having the following composition, in mole percent on the basis of the single oxides Al2O3, TiO2, MgO, and ZrO2: 90 < 2a + 3m < 110, 100 + a 2O3, t is the mole percent for TiO2, m is the molar percentage of ZrO2.</p> |
