Preparation and characterization of strontium zirconate (SrZrO3) fine powders

Synthesis of high-surface-area γ-Al2O3 from aluminum scrap and its use for the adsorption of metals: Pb(II), Cd(II) and Zn(II)

“…3) indicates that there is an inverse relationship between aging temperature and aging time. As reported in other studies [15,19], high temperature accelerates the formation of large crystals; thus at high temperature fewer grains are formed, allowing an orderly growth (nucleation process). According to Rinaldi [20], during aging, particles of aluminum hydroxide are solubilized and growth take place through condensation reactions; this growing process can be accelerated at high temperatures, leading to the formation of particles of large size.…”

“…The peak located at 761 cm −1 is assigned to the tetrahedral coordination AlO 4 [15]. The anion [Al(OH) 4 ] − is found at high pH and absorbs at 615 cm −1 [14].…”

The thermal decomposition of metal-organic precursors for epitaxial growth of SrZrO3 thin films

“…At this temperature all the reflections match with the reported orthorhombic structure of the SZO phase [20]. As a conclusion, the SZO formation take place in two steps, it starts around 650 • C and the pure phase is obtained at 900 • C. The same observations were evidenced when oxalates were used as precursors [21,22].…”

Novel photoluminescence of SrZrO3 nanocrystals synthesized through a facile combustion method

“…Several methods have been reported to prepare SrZrO 3 powders: conventional solid state reaction of SrCO 3 and ZrO 2 , coprecipitation, hydrothermal [7], sol-gel [8], and a method using single molecular (strontium zirconyl oxalate) precipitate as precursor [9]. In order to get homogeneous SrZrO 3 nanocrystals, the present study adopted a sol-gel combustion method, and introduced citric acid as chelator in the synthesis process and as fuel during the combustion process [10].…”
