Abstract:
1. A ceramic article, comprising a sintered phase non-silicate ceramic composition containing, as expressed on a weight percent oxide basis: 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 total porosity of the ceramic oxide composition is at least 40%, and wherein the sintered phase ceramic composition consists essentially of (a) aluminum titanate, zirconium titanate, and yttrium oxide, wherein 0.60≦a≦0.80 and 0.20≦b≦0.40 and 0.00≦c≦0.05, or (b) aluminum titanate and yttrium phosphate, wherein 0.5≦a≦0.95 and 0.05≦d≦0.5.
