Un método de taponar canales en un compuesto alveolado cerámico que comprende; (a) formar una mezcla comprendida de un líquido de dispersión y polvo cerámico, (b) insertar la mezcla en un extremo del canal en un compuesto alveolado cerámico no taponado, tal que la mezcla fluya al otro extremo, donde la mezcla se recoge y forma un compuesto alveolado cerámico taponado y (c) calentar el compuesto alveolado cerámico taponado a una temperatura suficiente para sinterizar el compuesto alveolado cerámico taponado para formar un compuesto alveolado cerámico taponado sinterizado poroso. A ceramic honeycomb wall-flow filter is prepared by plugging channels in a ceramic honeycomb by a method comprising the following. First, a mixture comprised of a dispersing liquid and ceramic powder is formed. Next, the mixture is inserted on one end of the channel in an unplugged ceramic honeycomb such that the mixture flows to the other end where the mixture collects and forms a plugged ceramic honeycomb. Then, the plugged ceramic honeycomb is heated to a temperature sufficient to sinter the plugged ceramic honeycomb to form a porous sintered plugged ceramic honeycomb.
