Оксидные порошки ZrO2-CeO2-Y2O3 для плазменного напыления термостойких термобарьерных покрытий

Abstract

A study of the synthesis conditions of ZrO2−CeO2−Y2O3 powders with a controlled granulometric composition was made. As a result, it was found that the optimal conditions for the co-precipitation of zirconium, yttrium, cerium hydroxides to obtain ZrO2 – 17 % CeO2 – 3 % Y2O3 powders with target fraction of 50 – 100 μm are: ammonia concentration of 13 mol/l, total metal concentration (Zr, Y, Ce) - 0.5 mol/l.
