Patent ID: 11447422

Abstract:
A batch composition containing pre-reacted inorganic spheroidal particles and pore-former spheroidal particles. The pre-reacted inorganic spheroidal particles have a particle size distribution wherein 10 μm≤DI50≤50 μm, and DIb≤2.0, and the pore-former spheroidal particles have a particle size distribution wherein 0.40 DI50≤DP50≤0.90 DI50, and DPb≤1.32, wherein DI50 is a median particle diameter of the distribution of pre-reacted inorganic spheroidal particles, DP50 is a median particle diameter of the pore-former particle size distribution, DIb is a breadth factor of the pre-reacted particle size distribution of the pre-reacted inorganic spheroidal particles, and DPb is a breadth factor of the pore-former particle size distribution. Also, green honeycomb bodies manufactured from the batch compositions, and methods of manufacturing a honeycomb body using the batch compositions, are provided.
