摘要: A high-purity semiconductor grade granular silicon composition, which can be produced in commercial quantities, is disclosed. In one embodiment the composition comprises a plurality of free-flowing particles having a total weight of at least about 300 kg and an average transition metal concentration of less than 0.2 ppba. In another embodiment the composition comprises a plurality of free-flowing silicon particles having a total weight of at least about 300 kg and at least 99 percent of the particles are between about 250 and 3500 microns in size.
