Resource type: Interactive Resource
Description: This interactive simulations of a SEM provides imaging for a sparkler sample. The simulation shows the affect of such settings as accelerating voltage, spot size, Z-depth, filament current, magnification, and astigmatism. The 'classic'" type of sparkler consists of a thin metal rod approximately 20 cm long that has been dipped in a thick batter of slow-burning pyrotechnic composition and allowed to dry. Metallic fuel, mandatory to make sparks consists of: (size of particles influences appearance of the sparks: aluminium or magnesium or magnalium, producing white sparks; iron, producing orange branching sparks; titanium, producing rich white sparks; ferrotitanium, for yellow-gold sparkles.
