CORDIERITE COMPOSITIONS FOR IMPROVED EXTRUSION PROCESS QUALITY

摘要

A green ceramic composition and a green ceramic body. The green composition and the body formed therefrom have sufficiently high wet strength to prevent formation of defects due to differential flow. The composition does not include calcined clays and comprises hydrated clays, cordierite precursors such as alumina, talc, and silica, and at least one binder. The binder can be present at a level that ranges from 3 wt% up to 10 wt%. A method of making a cordierite green body is also described.
