Abstract	Amorphous enstatite (MgSiO3) grains were produced by the simultaneous evaporation of SiO and Mg vapor by up and down double heaters method in Ar gas pressure of 10 Torr. Produced particles were mixture of MgO crystallites and amorphous MgSiO3 structure. High resolution electron microscopy showed the crystallites of MgO and MgSiO3 crystallites less than 10 nm. Crystallization of MgSiO3 amorphous structure have been determined by heating in vacuum.
