Short answer: Silicon metal is a grey brittle semi-metal used as the main alloying element in aluminium, the feedstock for solar polysilicon and the base for silicones, supplied in lump or powder at 97 to 99.5 percent purity so buyers match grade to aluminium, photovoltaic or chemical duty, with certificate and packing per export practice.
