Process for preparing submicronic powders of zirconium oxide stabilized with yttrium oxide.
摘要
<p>A process for preparing submicronic powders of zirconium oxide stabilized with yttrium oxide, by hydrothermal precipitation from solutions of zirconyl ions optionally containing yttrium ions and subsequent basification and calcination of the obtained hydrated oxides. The stabilizing yttrium ions may alternatively be added after hydrothermal precipitation of the hydrated zirconium oxide and before basification.</p>
