Effect of ball milling time on the synthesis of nanocrystalline merwinite via mechanical activation and heat treatment

  • Masoud Hafezi , Ali Nadernezhad , Maryam Mohammadi , Hadi Barzegar and Hossein Mohammadi


Nanocrystalline merwinite was successfully synthesized by mechanical activation of a mixture of magnesium hydroxide, calcium oxide and silica gel powders followed by heat treatment. The phase development and various physical properties were investigated as a function of milling time using X-ray diffraction, scanning electron microscopy, simultaneous thermal analysis, particle size analysis and transmission electron microscopy. The results showed that formation of merwinite in annealed powders was enhanced by increasing the milling time. Nanocrystalline merwinite powder with an average crystallite size of about 36 nm was obtained after 30 hours of ball milling and subsequent annealing in 900 °C for 1 hour.
