Abstract
Glass-bonded ceramics made of non-microcracked non-oxide or oxide ceramic particles which are bound together by glass into a unitary non-microcracked structure are disclosed. Such ceramics are suitable for use in substrates and filters, such as a diesel particulate filter.
Claims6
A glass-bonded ceramic honeycomb structure having a porosity in the range 40 to 60%, a median pore size in the range 7 to 30 microns, and a non-microcracked microstructure comprising non-microcracked ceramic particles bound together into an interconnected porous network by a preformed glass phase comprising substantially no microcracks.
