Abstract
Abstract
Particulate matter (PM) from vehicle exhaust can be effectively removed by cordierite particulate filters. The pore size and distribution of the cordierite particulate filter are very important to PM trapping efficiency. The main factors affecting the pore formation of porous cordierite ceramics are the grain size of the feedstock, the size of pore-forming agent particles, the sintering process, etc. Talc, kaolin, silicon oxide, alumina, and boehmite were used as the raw materials, and the effects of starch pore formers of different particle sizes on the CTE, XRD, microstructure, pore size distribution, and mechanical strength of honeycomb cordierite were investigated.
