| 内容： | A method of producing a ceramic component includes dispersing an alpha-alumina nanopowder whose diameter is above 100 nm in water, using 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTC) or 4,5-Dihydroxy-m-benzenedisulfonic Acid, Disodium Salt (Tiron TM ) as dispersant, shifting the pH towards the isoelectric point (IEP) by adding a mixture of acetic anhydride and ethylene glycol, or polyethylene glycol, drying in a controlled atmosphere (humidity, temperature) and post compacting using cold isostatic pressing and sintering the three-dimensional structure thus formed. |
