Economical synthesis of nano alumina powder using an aqueous sol–gel method

Compressibility and sinterability of Al2O3–YAG nanocomposite powder synthesized by an aqueous sol–gel method

“…In addition, it provides powders with low sintering temperatures and uniform particle sizes [16]. Recently new and economical procedures have been developed for synthesis of nano alumina using Al powder and AlCl 3 [2,17]. In the present work, Al 2 O 3 -YAG nanocomposite powder was synthesized using the same raw materials in their works and Y 2 O 3 through a sol-gel method.…”

Gelling and phase inversion preparation for Al2O3/PVDF hybrid membrane

“…PVDF can be used as composites with these inorganic nanoparticles to improve the membrane separation performance, thermal ability, and membrane forming ability by the combination of the basic properties of organic and inorganic materials. The strong affinity to water makes Al 2 O 3 nanoparticles the best candidate material for hydrophilic modification of PVDF membrane [24]. We drew a conclusion that PVDF and Al 2 O 3 are not connected by chemical bonds from the previous report, that is to say, they have insufficient combination strength in membrane, which results in low tensile strength of the membrane.…”

Nano Aluminum Oxides as Adsorbents in Water Remediation Methods: A Review

“…ammonia as the precipitating agent and the gel resulted was digested for 30 hours, filtered, dried and annealed at 1000 o C. 41 These methods based on physical and /or chemical processes, have one or other disadvantage and moreover, they are tedious, costly, involve toxic chemicals and hazardous to the environment. 42 Hence, researchers are investigating green methods of synthesis to meet the industrial demand of the Al2O3 nanoparticles.…”
