A composition is disclosed comprising a fine zircon component having a median particle size of less than 5 μm, a medium zircon component having a median particle size of from 5 μm to 15 μm, and a sintering aid, wherein the composition, after firing, has a strain rate of less than about 1×10 −6 /hr. A method for making a green body comprising contacting a fine zircon component having a median particle size of less than 5 μm, a medium zircon component having a median particle size of from 5 μm to 15 μm, and a sintering aid, and then forming the mixture into a desired shape is disclosed. |
