摘要:
A mullite body comprising: a plurality of crystals, wherein about 70 percent or greater of the crystals have a crystal diameter that is within about 3 microns or less of an average diameter of the plurality of crystals, and a porosity of 55 percent or greater; and made using a process comprising: mixing precursor materials together with an average aggregate particle size of about 3 microns or smaller measured using a particle size analyzer; heating greenware in air to a first temperature such that the greenware is dried and forms calcineware, heating the calcineware in a silicon tetrafiouride atmosphere to form flurotopaz, and heating to a second temperature so that a mullite structure is formed.
