Patent ID: 7932201

Claim:
A porous non-silicate ceramic article comprised of a composition containing, as expressed on a weight percent oxide basis: a (Al 2 TiO 5 )+ b (ZrTiO 4 )+ c (Y 2 O 3 )+ d (YPO 4 ) wherein a, b, c, and d are weight fractions of each component such that (a+b+c+d)=1.00, and wherein 0.5<a≦0.95; 0≦b≦0.5, 0.0≦c≦0.10, and 0≦d≦0.5, and wherein the composition comprises zirconium titanate or yttrium phosphate, and wherein the total porosity of the ceramic oxide composition is at least 40%.
