SILICON CARBIDE POROUS BODY AND ITS PRODUCTION METHOD, AND BRAKE FILTER WITH THE SILICON CARBIDE POROUS BODY
To provide a silicon carbide porous body capable of securing particle collection performance and a performance of prevention of particle flying, and returning the inside of a container to atmospheric pressure during a short time in a silicon carbide porous body suitable for a brake filter installed at a gas introduction port, for returning the inside of the container under reduced pressure to atmospheric pressure.SOLUTION: A silicon carbide porous body includes: a plurality of silicon carbide particles 2 that form a skeleton by bonding and forms a plurality of pores; and a neck part 3 formed by surface contact of adjacent the silicon carbide particles, in which an average pore diameter is 3 μm or larger and 9 μm or smaller, and the porosity is 35% or larger and 55% or smaller.SELECTED DRAWING: Figure 1
【課題】減圧下の容器内を大気圧に復帰させるために、ガス導入口に設置されるブレイクフィルタに好適な炭化珪素質多孔体において、パーティクル捕集性能、及びパーティクル舞い上がり防止性能を確保するとともに、容器内を短時間のうちに大気圧に復帰させることのできる炭化珪素質多孔体を提供する。【解決手段】結合することにより骨格をなすとともに、複数の気孔を形成する複数の炭化珪素粒子２と、隣接する前記炭化珪素粒子同士が面接触することにより形成されたネック部３と、を有し、平均気孔径が３μｍより大きく９μｍ以下であって、気孔率が３５％以上５５％以下である。【選択図】図１
