PRODUCTION OF SELF-SUPPORTING CERAMIC MATERIALS HAVING A REDUCED THICKNESS AND CONTAINING METAL OXIDES |
摘要 |
The invention relates to a method for producing a ceramic material containing metal oxide, including the following consecutive steps consisting in: (a) supplying a flash-sintering device with a nanocrystalline powder comprising crystallites and crystallite agglomerates of a material having formula Zr1-XMxO2, wherein M is selected from yttrium, scandium and cerium, or Ce1-XM'XO2 wherein M' is selected from gadolinium, scandium, samarium and yttrium, in which x is between 0 and 0.2, said powder having an average crystallite size of between 5 and 50 nm, an average crystallite-agglomerate size of between 0.5 and 20 µm, and a specific surface area of between 20 and 100 m2/g; and (b) flash-sintering said powder by applying a pressure of between 50 to 150 MPa at a temperature of between 850° C and 1400° C for a period of 5 to 30 minutes. |
