A study on crystallization of amorphous nano silica particles by mechanical activation at the presence of pure aluminum

Mechanical crystallization of amorphous nano silica particles through ball milling of Aluminum-amorphous silica powder at room temperature resulted in crystalline silica with an average size of about 30 nm. A diffusion induced mechanism based on mechanical activation assisted diffusion of aluminum atoms in to amorphous silica was proposed for mechanical crystallization of amorphous silica.331
