4N Polysilicon

Appearance: Grey metal with metallic luster.
 
 
Purity: 4N
 
Si≮99.99%, resistance 0.02-0.2 ohm
 
Application: Polycrystalline silicon is the direct material to produce crystalline silicon, and it is the basic material of contemporary artificial intelligence, auto control, information disposal, photo electricity, and other semiconductor parts. Polycrystalline silicon of high pure dense and high quality is an important material of the production of silicon ductor parts and IC.
