Scope

This document describes a method for determining the oxygen content in photovoltaic silicon materials by pulse heating inert gas melting and infrared absorption.
This document is suitable for determining the oxygen content in photovoltaic silicon materials such as silicon powder, industrial silicon, and granular polycrystalline silicon used in the production of polycrystalline silicon. The measurement range is 0.0010% to 0.40% by mass of oxygen. Other types of crystalline silicon materials used in the production of photovoltaic modules can be used as reference for this method.
