| 摘要 |
A heat densifiable composition comprised essentially of: A) a chemically derived densifiably reactive spinel, b) one or more zirconium oxide phases, c) one or more zirconium oxide phase-stabilizing agents, and/or d) refractory oxides, carbides, or nitrides as stress-absorbing property modifiers; wherein the densifiable reactive spine is derived by decomposition of a precursor produced by the chemical precipitation or crystallization of the desired spinel forming metals from an intimate mixture of at least one soluble metal salt. Processes for preparing the composition are also disclosed. |
