Impregnation of ceramic composites
A process for the post-treatment of an electroceramic composite material is disclosed. The process comprises introducing an electroceramic composite material and a flowable organometallic compound into a pressure chamber, and degassing (1) the electroceramic composite material by creating a vacuum or negative pressure in the pressure chamber while immersing (2) the electroceramic composite material in the organometallic compound. The pressure is then raised to atmospheric pressure, wherein the flowable organometallic compound is absorbed (3) into at least part of the pores of the composite material. Then, the electroceramic composite containing the organometallic compound absorbed into the pores is treated (4) with water, water vapor and/or other chemicals, thereby producing a metal oxide impregnated electroceramic material containing the solid metal oxide absorbed into the pores. Alternatively to flowable organometallic compounds, a suspension of metal or metal oxide nanoparticles may be used for post-treatment.
公开了一种用于电陶瓷复合材料的后处理的工艺。该工艺包括将电陶瓷复合材料和可流动有机金属化合物引入压力室，以及通过在压力室中产生真空或负压来对电陶瓷复合材料进行脱气(1)，同时将电陶瓷复合材料浸入(2)所述有机金属化合物中。然后将压力升高至大气压，其中所述可流动有机金属化合物被吸收(3)到复合材料的至少部分孔中。然后，用水、水蒸气和/或其他化学物质处理(4)含有吸收到所述孔中的所述有机金属化合物的电陶瓷复合材料，从而产生含有吸收到所述孔中的固体金属氧化物的金属氧化物浸渍电陶瓷材料。作为可流动有机金属化合物的替代，可以使用金属或金属氧化物纳米颗粒的悬浮液进行后处理。
