Qinghai Crystalline Silicon Materials Collaborative Cluster

The corridor produces both high-purity polysilicon feedstock and monocrystalline ingots for wafer processing are the principal outputs of crystalline Silicon Materials in Xining–Haidong crystalline-silicon corridor. Upstream work depends on metallurgical silicon and chlorosilanes support purification, qualified polysilicon is then loaded into crystal-pulling furnaces with quartz crucibles and seed crystals, followed by distillation and reduction purify silicon feedstock before Czochralski growth and ingot shaping downstream. The demand side is ingot plants consume purified silicon, while wafer shops procure crystals by geometry and electrical properties.
