Abstract
A slurry composition includes, by volume, a ceramic composition in an amount of from about 60 to about 75 percent and a binder in an amount of from about 25 to about 40 percent, plus a platinum group metal catalyst and a dopant. The ceramic composition includes, by volume of the ceramic composition, fine fused silica particles having a particle size d50 of from about 4 μm to about 7 μm, in an amount of from about 7 to about 40 percent; coarse fused silica particles having a d50 of from about 25 μm to about 33 μm, in an amount of from about 29 to about 60 percent; inert filler particles having a d50 of from about 5 μm to about 25 μm, in an amount of from about 8 to about 40 percent; and fumed silica particles, in an amount of up to about 15 percent.
