초록

The invention provides a high temperature, damage tolerant candle filter (4) made of a porous ceramic material which is designed so that, if it fails, it does not fail catastrophically. The ceramic candle filter includes a hollow tube (14) having an open end, a closed end and a porous outer wall therebetween. The porous wall is made of a fiber ceramic reinforcement material impregnated with ceramic particles and a fugitive material that is substantially removed from the fiber ceramic reinforcement material or partially converting into a permeable materia...
