professional factory for Coral-Shaped Polycrystalline Silicon Blocks - Purchasing & Recycling Polysilicon – UrbanMines

Monocrystalline Silicon, Compacted Materials, Clean-Free

Silicon blocks , of which quality indicators are in line with contractual requirements. The appearance and surface of the materials are compact and smooth. There maybe cracks with depths below 3 mm but no interlayers exist.

Monocrystalline Silicon,Cauliflower Materials,Clean-Free/Cleaning Necessary

Cauliflower-shaped polysilicon material. Cauliflower form and surface attach the polycrystalline silicon raw material of oxide. “Cauliflower” silicon particles are likely formed by aggregation of smaller silicon nanoparticles and are in an intermediate state in the evolution toward large crystalline particles. These “cauliflower” silicon particles consist of nano-domains of crystalline and amorphous silicon (a-Si) of which the latter exhibits photoluminescence. The surface of the material is quite clean after being washed, no oxide or other impurities remain in the gaps, cauliflower-shaped materials are removed thoroughly, production requirements of ingot casting in a furnace or crystal pulling can be met under a standard procedure.

Monocrystalline Silicon, Coral Materials,Cleaning-Free

Silicon blocks. For materials with appearance and surface that are neither compact nor smooth or in which there are cracks with depths of above 3mmt if the quality of such materials is in line with contractual requirements such materials shall be classified as coral materials regardless of ratios.
