Preparation and Characterization of Molarity Based ZnO Fine Powder by Hydrothermal Synthesis Zon Cho Cho Hmway Htet Htet Nwe Yin Maung Maung Than Than Win Crystalline zinc oxide fine powder has been prepared by hydrothermal method. Hydrothermal synth esized zinc oxide powder was prepared with zinc acetate dihydrate (Zn(CH3COO)2.2H2O) and sodium hydroxide (NaOH), and methanol (CH3OH) employed as solvent. Samples were prepared at different molarities (0.2 – 0.5) M for 6 h. Teflon-lined stainless steel container was used as a hydrothermal vessel. The temperature for synthesizing zinc oxide powder was around 120°C lower than that of conventional heating process. Subsequently, Xray diffraction (XRD) was used to examine the phase formation and crystallographic properties of ZnO specimens. The concentration of zinc in zinc oxide was characterized by energy dispersive X-ray fluorescent (EDXRF). The results indicate that zinc oxide powder synthesized by hydrothermal method was fine powder. 2016 http://hdl.handle.net/20.500.12678/0000002351 https://meral.edu.mm/records/2351
