Managed pore size distribution in honeycomb substrates

摘要

The disclosure is directed to a method for managing pore size distribution in honeycomb substrates by using two or more pore forming agents in the batch ingredients. In particular, the disclosure is particularly useful in managing pore size distribution in cordierite and aluminum titanate honeycomb substrates in the face of particle size variations in the pore forming agents and other materials used to make such substrates.
