Abstract:
1. A ceramic body having a composition comprising a(Al 2 O 3 .TiO 2 )+b(CaO.Al 2 O 3 .2SiO 2 )+c(SrO.Al 2 O 3 .2SiO 2 )+d(BaO.Al 2 O 3 .2SiO 2 )+e(3Al 2 O 3 .2SiO 2 )+f(Al 2 O 3 )+g(SiO 2 )+h(Fe 2 O 3 .TiO 2 )+i(MgO.2SiO 2 ), wherein a, b, c, d, e, f, g, h, and i are weight fractions of each component such that (a+b+c+d+e+f+g+h+i)=1, wherein 0.5<a≦0.95; 0≦b≦0.5; 0≦c≦0.5;0≦d≦0.5; 0<e≦0.5; 0≦f≦0.5; 0≦g≦0.1; 0≦h≦0.3; 0≦i≦0.3; b+d>0.01.
