Product Description
Physicochemical property
Polysilicon is gray metallic luster, Density 2.32~2.34g/cm3. Melting point 1410℃. Boiling point 2355℃. dissolved in mixed acid of hydrofluoric acid and nitric acid. insoluble in water, nitric acid and hydrochloric acid. It is not active at normal temperature, React with oxygen, nitrogen, sulfur and so on at high temperature. High temperature melting state, has a large chemical activity, almost can interact with any material. With semiconductor properties, it is a very important and excellent semi-conductive material. Electronics industry is widely used.
Polysilicon/monocrystalline silicon difference
Polysilicon is the direct raw material for the production of monocrystalline silicon. The difference is mainly manifested in physical properties. For example, the mechanical properties, optical properties and thermal properties are far less obvious than monocrystalline silicon;In terms of electrical properties, the electrical conductivity of polysilicon is far less significant than that of monocrystalline silicon, or almost no electrical conductivity. In terms of chemical activity, the difference between the two is minimal.
