“…Besides the conventional synthesis method, several techniques have been reported for the preparation of LSGM materials: ultrasonic spray pyrolysis, 8 glycine-nitrate combustion synthesis, 9 sol-gel method, 10 Pechini method. 11 As reported by Kriven and coworkers, [12][13][14][15] a so-called steric entrapment synthesis method (SES) with inexpensive polymer, polyvinyl alcohol (PVA), is an efficient way for the preparation of mixed oxides. Highly reactive, highly sinterable, oxide powders have been synthesized by this method.…”

“…Equivolumetric, triplex, 33 vol% Al 2 O 3 –33 vol% yttrium aluminum garnet (YAG)–33 vol% ZrO 2 composite powder was synthesized using the organic, steric entrapment method 32–48 . Aluminum nitrate nonahydrate [Al(NO 3 ) 3 ·9H 2 O, 98+%, Aldrich Chemical Inc.], zirconium (IV) propoxide [Aldrich Chemical Inc., Milwaukee, WI, 70 wt% solution in 1‐propanol], and yttrium nitrate hexahydrate [Y(NO 3 ) 3 ·6H 2 O, 99%, Aldrich Chemical Inc.], were used as Al +3 , Zr +4 , and Y +3 sources, respectively.…”

Three‐phase (triplex) ceramic composites with improved thermal stabilities resulting from minimized grain growth due to extended grain separations are introduced. Al2O3, yttrium aluminum garnet (YAG, Y3Al5O12), and ZrO2 were chemically compatible to make a stable triplex composite. Another stable composite could be made due to chemical compatibility among Al2O3, NiAl2O4, and 3 mol% yttria‐tetragonal zirconia polycrystals (3Y‐TZP). The composites of 33 vol% Al2O3–33 vol% YAG–33 vol% ZrO2, 33 vol% Al2O3–33 vol% NiAl2O4–33 vol% 3Y‐TZP, and 50 vol% Al2O3–25 vol% NiAl2O4–25 vol% 3Y‐TZP were fabricated using either sintering or hot pressing procedures. The sintered 33 vol% Al2O3–33 vol% YAG–33 vol% ZrO2 and 33 vol% Al2O3–33 vol% NiAl2O4–33 vol% 3Y‐TZP composites demonstrated a “self accommodating sintering effect” having a wide sintering range without any extensive change in properties. Annealing of the 33 vol% Al2O3–33 vol% NiAl2O4–33 vol% 3Y‐TZP composite at 1600°C for 50 h resulted in higher strength retention after heat treatment compared with that expected from the sum of the strengths of constituent phases. This was attributed to a mutual, grain growth retardation effect. Chemical compatibilities, mechanical properties, microstructures, and thermal stabilities of the composites were studied.

“…Two different kinds of in situ duplex (two phase) composites of 50 vol% Al 2 O 3 –50 vol% NiAl 2 O 4 , and 71 vol% Al 2 O 3 –29 vol% NiAl 2 O 4 were chemically fabricated by the organic, steric entrapment method 9–15 . Appropriate amounts of aluminum nitrate nonahydrate (Al(NO 3 ) 3 ·9H 2 O, 98+%, Aldrich Chemical Inc., Milwaukee, WI) and nickel hexahydrate (Ni(NO 3 ) 2 ·6H 2 O, Aldrich Chemical Inc.) were used as chemical sources for Al 3+ and Ni 2+ , respectively.…”

Multiphase ceramic composites with improved mechanical properties and high‐temperature stabilities resulting from minimized grain sizes due to extended diffusion distances are introduced. Four‐phase (quadruplex) composites of 25 vol% Al2O3–25 vol% NiAl2O4–25 vol% TiC–25 vol%“ZrO2”; 30 vol% Al2O3–30 vol% NiAl2O4–10 vol% TiC–30 vol%“ZrO2”; and 50 vol% Al2O3–20 vol% NiAl2O4–10 vol% TiC–20 vol%“ZrO2” as well as a five‐phase (quintuplex) composite of 20 vol% Al2O3–20 vol% TiB2–20 vol% TiC–20 vol% ZrB2–20 vol%“ZrO2” were fabricated using hot‐pressing procedures. The 25 vol% Al2O3–25 vol% NiAl2O4–25 vol% TiC–25 vol%“ZrO2”‡ composite, hot pressed at 1600°C for 1 h in an Ar atmosphere, had three‐point bend strength, hardness, and toughness values of 984 MPa, 1251 kg/mm2, and 4.74 MPa·m1/2, respectively. The chemically compatible, quintuplex composite consisting of 20 vol% Al2O3–20 vol% TiB2–20 vol% TiC–20 vol% ZrB2–20 vol%“ZrO2” was hot pressed at 1800°C in an Ar atmosphere for 5 h and it had hardness, bend strength, and toughness values of 1707 kg/mm2, 714 MPa, and 5.12 MPa·m1/2, respectively. The four‐ and five‐phase composites, heat‐treated under an Ar atmosphere at 1600°C for 100 h, each showed high‐temperature stabilities without any severe changes in the microstructural and mechanical properties.
