Abstract
There is provided a coating material for a honeycomb structure, the coating material including inorganic particles or organic particles having D90/D10 of 5 to 50 with D10 of 50 μm or less and D90 of 4 μm or more (wherein D10 and D90 are values of 10% diameter and 90% diameter, respectively, in volume-based integrated fraction of a particle diameter distribution measured by a laser diffraction/scattering method from the smaller particle diameter side).
Claims5
A coating material for a honeycomb structure, comprising inorganic particles, all of which have a D90/D10 of 5 to 50, with a D10 of 50 μm or less and a D90 of 4 μm or more;
- wherein D10 and D90 are values of 10% diameter and 90% diameter, respectively, in a volume-based integrated fraction of a particle diameter distribution measured by a laser diffraction/scattering method from the smaller particle diameter side;
- wherein the inorganic particles have a long axis/short axis ratio of 1.3 to 4.0;
- and
- wherein the coating material contains at least one kind of inorganic particles selected from the group consisting of silicon carbide, silicon nitride, boron nitride, alumina, mullite, alumina silicate, magnesium silicate, zirconia, zirconium phosphate, alumina titanate, and titania.
