METHOD OF PRODUCING CERAMIC GRADIENT MATERIAL Russian patent published in 2012 - IPC B22F3/12 C04B35/64 C22C1/10

Abstract RU 2454297 C1

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, in particular, to production of gradient ceramic zirconium-based materials. Fine powder consisting of solid ZrO₂-based solutions with components dissolved therein and selected form the group of tetragonal-phase stabiliser oxides is subjected to compaction at 550-800 MPa and sintering at 1500-1700°C with maturing for 1-5 h.

EFFECT: higher resistance to thermal effects.
