“…Homogeneous precipitation 39 has been adopted to prepare nanoparticles with a narrow distribution such as c-Al 2 O 3 nanoparticles, 40 CeO 2 nanoparticles, 41 and a series of metal hydrous oxides. 42 The particle sizes were effectively controlled in a narrow range.…”

Disperse fine equiaxed α‐Al2O3 nanoparticles with a mean particle size of 9 nm and a narrow size distribution of 2–27 nm were synthesized using α‐Fe2O3 as seeds and isolation via homogeneous precipitation‐calcination‐selective corrosion processing. The presence of α‐Fe2O3 acting as seeds and isolation phase can reduce the formation temperature to 700°C and prevent agglomeration and growth of α‐Al2O3 nanoparticles, resulting in disperse fine equiaxed α‐Al2O3 nanoparticles. These α‐Al2O3 nanoparticles were pressed into green compacts at 500 MPa and sintered first by normal sintering to study their sintering behavior and finally by two‐step sintering (heated to 1175°C without hold and decreased to 1025°C with a 20 h hold in air) to obtain nanocrystalline α‐Al2O3 ceramics. The two‐step sintered bodies are nanocrystalline α‐Al2O3 with an average grain size of 55 nm and a relative density of 99.6%. The almost fully dense nanocrystalline α‐Al2O3 ceramic with finest grains achieved so far by pressureless sintering reveals that these α‐Al2O3 nanoparticles have an excellent sintering activity.

“…This can be done either by a change in pH, use of an oxidizing agent to destroy the complexing reagent, or by temperature. Ethylenediaminetetraacetic acid [(ethylenedinitrilo )tetraacetic acid] complexes have been thus utilized (17,24,28). The silver-ammonia complex has been dissociated with hydrogen ion resulting from the slow hydrolysis of an ester (14)• By the other method, a cation may be converted from one oxidation state to the desired one.…”
