Synthesis of cubic MgO nanostructure by an easy hydrothermal-calcinations method

Cubic MgO micro-particles with approximately 5-10 µm dimensions were synthesized indirectly from magnesium salt solutions through three consecutive steps, namely: wet chemical precipitation, hydrothermal and thermal dissociation. In wet chemical precipitation step Mg(OH)2 uniform lamellar hexagonal...

Summary:Cubic MgO micro-particles with approximately 5-10 µm dimensions were synthesized indirectly from magnesium salt solutions through three consecutive steps, namely: wet chemical precipitation, hydrothermal and thermal dissociation. In wet chemical precipitation step Mg(OH)2 uniform lamellar hexagonal nano-structure with about 30 nm in thickness were synthesized from 0.2 M Mg(NO3)2 • 6H2O solution, subsequent hydrothermal processing of synthesized Mg(OH)2 lamellar hexagonal nano-structure in 10, 20, 30, 60, 120 and 180 min produced 5-10 µm MgCO3 micro-cubes which calcinations of these particles leads to production of the same size MgO micro-cubes. Most pure MgCO3 micro-cubes were synthesized after 120 min of hydrothermal processing. STA analysis revealed that the best temperature for calcinations is about 700℃. KCI Citation Count: 3
