摘要： The invention relates to a method of obtaining porous ceramics. More specifically, the invention relates to a method of producing a porous ceramic piece, comprising the following successive steps: (a) preparation of a mixture M containing a suspended ceramic powder, at least one gelling agent and at least one foaming agent, at a mixing temperature greater than the gelling temperature of the gelling agent; b) shearing of mixture M at a foaming temperature greater than the gelling temperature, until a foam is obtained; c) gelling of the foam, consisting in cooling mixture M to a temperature lower than the gelling temperature of the gelling agent and d) drying of the gelled foam such as to obtain a preform. According to the invention, a stabilising agent is added to mixture M, said agent having a viscosity which increases by at least a factor ten when a shearing speed of the stabilising agent falls from 100 s-1 to 0 s-1.
