Abstract: In order to provide a ceramic fiber board which does not emit smoke and does not cause a problem of shedding of particles even when used in a high-temperature environment, the invention provides a method of producing a ceramic board which uses ceramic fibers containing Al2O3 and SiO2 as a raw material, in which a mixed liquid (Na2O×3SiO2) of SiO2 sol and water glass is used as an inorganic binder, in which weight ratio in terms of the solid contents of SiO2 and water glass is SiO2: 89 to 35% and water glass: 11 to 65%.

Abstract: In a ceramic setter plate 10 of a plate-shaped sintered body 12 of a non-oxide ceramic material formed by firing ceramic particles 11 of at least one selected from the group consisting of SiC, Si3N4, BN, AlN, MoSi2, TiN and ZrB2, the sintered body 12 is composed of a porous body 12 having interconnected pores 15 and one or more cavities 13 inside thereof in substantially the center in the thickness direction of thereof, at least one of the cavities 13 has therein one or a plurality of branched parts 17, the cavities 13 have opening parts 14 at side parts of the sintered body 12. The ceramic setter plate has good gas permeability for firing a laminate of ceramic green sheets, for which the firing efficiency is good, and for which repeated use is possible.
