Patent ID: 8063120

Claim:
A ceramic powder, comprising first particles having a maximum particle size of from 12 to 30 μm, and second particles having a maximum particle size of from 2 to 7 μm, wherein an amount of said first particles is from 39 to 48% by mass, an amount of said second particles is from 17 to 26% by mass, an amount of particles having a particle size of greater than 7 to less than 12 μm is from 8 to 13% by mass, relative to the total mass of the ceramic powder, and said ceramic powder has a multiple peak-frequency type particle size distribution which has at least two peaks, as determined according to a laser diffraction-scattering type particle size distribution analyzer, a maximum particle size observed for the first peak falls within the range of 12 to 30 μm, a maximum particle size observed for the second peak falls within the range of 2 to 7 μm, and a ratio (F2/F1) of the frequency value F2 of the maximum particle size observed for the second peak to the frequency value F1 of the maximum particle size observed for the first peak ranges from 0.6 to 1.0.
