Hi Everyone,

It Works!. What is most important about this press release (see link below) is that we demonstrated that the PUREVAP process succeeded in removing an impressive amount of impurities as we reduced quartz (SiO2) to make Silicon (Si). The amount of Boron (B) that was removed was a total surprise. Boron is notoriously difficult to remove from Silicon Metal. In fact, it was more likely for B it to be concentrated!

Also note, these were blind tests. With these results in hand, Pyrogenesis can now work to improve the PUREVAP process for the next series of tests.

If you have any questions, please do not hesitate to contact me or Bernard.

Regards

Patrick
