Abstract
The invention provides a process of making porous structures or materials, including the colloidal processing (e.g. slip casting, pressure casting, tape casting or electrophoretic deposition) of solid particle emulsions to form a green body that can be directly sintered without a de-binding step.
Claims16
A process for producing a porous ceramic or metallic body from a ceramic or metallic green body, comprising the steps of:
- making a stabilised solid particle emulsion from a combination of at least two immiscible liquids, and solid ceramic or metallic particles, wherein said solid ceramic or metallic particles form a layer onto or are densely packed at the interface of said at least two immiscible fluids,
- colloidal processing of solid particle stabilised emulsion to form a ceramic or metallic green body, and
- directly sintering said ceramic or metallic green body.
