PUREVAPTM

Developed by PyroGenesis, PUREVAPTM is a patent pending one-step proprietary process that uses a plasma arc within a vacuum furnace to produce high purity metallurgical grade silicon and solar grade silicon from quartz. It is expected that the silicon grades produced by PUREVAPTM could be used for different applications, including solar energy.

Features & Benefits of PUREVAPTM:

  • One-step direct transformation process;
  • Lower cost for producing silicon compared to current practices;
  • Lower CO2 than current processes;
  • Remove impurities: Phosphate, Potassium, Magnesium, Zinc, Calcium, and other elements.

 

PUREVAP<sup>TM</sup> - High Purity Silicon

PUREVAPTM reduces the quartz with carbon using a plasma submerged arc. Under vacuum, and at very low operating pressure, the silicon is refined in a one-step process removing all impurities and transforming it to its purest form, resulting in a high purity silicon.
