Batch compositions comprising pre-reacted inorganic particles and methods of manufacture of green bodies therefrom

A method of manufacturing a honeycomb body, comprising:

• mixing a batch mixture comprising pre-reacted inorganic spheroidal particles having a particle size distribution of:
• 20 μm≤D50≤50 μm,
• D90≤100 μm, and
• D10≥5 μm,
• less than 20 wt % of fine inorganic particles by super-addition to a total weight of the pre-reacted inorganic spheroidal particles in the batch mixture, the fine inorganic particles having a median diameter of less than 5 μm, and
• LV %>28 in wt % by super-addition to all inorganic particles in the batch mixture,
• wherein 90% of the pre-reacted inorganic spheroidal particles have a diameter of less than D90, 10% of the pre-reacted inorganic spheroidal particles have a diameter of less than D10, and D50 is a median particle diameter;
• and
• shaping the batch mixture into a wet green honeycomb body by extrusion wherein the batch mixture comprises Tau Y/Beta >2.0, wherein Tau Y is a measure of batch stiffness and Beta is a friction coefficient of the batch mixture.
