Abstract
A study is reported of the effects of the form taken by impurities in silicon on quantitative determinations. The limit of detection for 1 g samples is established for several impurities. Radioactive isotopes have been used to show that the conditions of distillation cause very volatile impurities to evaporate completely, though between 10 and 30% may condense outside the central capsule. This dispersal has been observed also for a nonvolatile base (zirconia). It is shown that the degree of condensation depends very little on the impurity content down to 5×10−10 g in a nonvolatile base. Boron shows some unusual features.
