Title:
BATCH COMPOSITIONS COMPRISING PRE-REACTED INORGANIC PARTICLES AND METHODS OF MANUFACTURE OF GREEN BODIES THEREFROM
Document Type and Number:
Japanese Patent JP2023160939
Kind Code:
A
Abstract:
To provide fast-extrudable batch compositions, green honeycomb bodies based on the batch compositions, and methods of manufacturing the same.SOLUTION: Batch compositions contain pre-reacted inorganic spheroidal particles, small amount of fine inorganic particles ("fines"), and an extremely large amount of liquid vehicle. The batch compositions contain pre-reacted inorganic particles having a particle size distribution with 20 μm≤D50≤100 μm, D90≤100 μm, and D5≥10 μm; less than 20 mass% of fine inorganic particles (fines) whose particle distribution(s) have a median diameter of less than 5 μm; and a liquid vehicle in a mass percent (LV%≥28%) by super-addition to all inorganic particles in the batch composition. Fast extruding batch compositions having extremely high Tau Y/Beta ratios are provided. Green bodies, such as green honeycomb bodies, and methods of manufacturing the green honeycomb bodies are provided, as are other aspects.SELECTED DRAWING: Figure 4B
