IMPREGNATION OF CERAMIC COMPOSITE MATERIAL
A process for post-treatment of electroceramic composite material is disclosed. The process comprises introducing electroceramic composite material and flow-able organometallic compound to a pressure chamber, and degassing (1) the electroceramic composite material by creating a vacuum or underpressure in the pressure chamber, while the electroceramic composite material is immersed (2) in said organometallic compound. Then the pressure is elevated to an atmospheric pressure, wherein said flowable organometallic compound is absorbed (3) into at least part of the pores of the composite material. The electroceramic composite material containing said organometallic compound absorbed into said pores, is then treated (4) with water, water vapour and/or other chemical, thereby producing metal oxide impregnated electroceramic material containing solid metal oxide absorbed into said pores. Instead of flowable organometallic compound, a suspension of metal or metal oxide nanoparticles may be used for the post-treatment.
