Description

Technical Field

[0001] The utility model relates to the technical field of polysilicon classification, and specifically relates to a polysilicon classification device. Background Technique

[0002] Polysilicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooled conditions, silicon atoms arrange in a diamond lattice form to form many crystal nuclei. If these crystal nuclei grow into grains with different crystal plane orientations, then these grains combine to crystallize into polysilicon. Polysilicon can be used as the raw material for pulling single crystal silicon. The differences between polysilicon and single crystal silicon are mainly manifested in physical properties. For example, in terms of the anisotropy of mechanical properties, optical properties, and thermal properties, it is far less obvious than single crystal silicon; in terms of electrical properties, the conductivity of polysilicon crystals is also far less significant than that of single crystal silicon, and even has almost no conductivity. In terms of chemical activity, the difference between the two is extremely small.

[0003] Currently, the Chinese patent with the publication number CN202220954527.8 discloses a feeding device for a polysilicon crushing and screening machine.
