It is not because we do our DD and have a different opinion that we are basher;
Chalenge here is scalling up the technology and adoption by the industry;
Hope everyone the best - Was my post in 2015.
" Plasma technology for upgraded mgSi to UMG quality is not new and in lab scale does work. The problem is that the high surface contact you need to purify mgSilicon makes it impractical in an industrial scale, which is why these “revolutionary” processes that have been tried before have not taken off. We were involved in our previous life with using this technique at a silicon metal producer. We adapted an furnace with plasma and used it to purify silicon in a vacuum induction furnace. Again, the issue is that you must put the plasma in contact with a relatively huge volume of silicon in order to treat the entire batch and this is impractical.
Using quartz in a vaporization reactor is also something that has been worked on in the past years and basically is a derivative technology from the titanium sector. I am not sure of the industrial applicability mainly because the economics of scale for standard mgSilicon and polysilicon production are so large. As well, the production costs of such a new technology that is highly unproven will have to compete with ever lower production costs of Polysilicon. "
That DD comment was given to me by an executive who has more than 20 years experience in the industry:
Executive Director which specializes in industrial process design, knowhow transfer and engineering for metallurgical silicon and solar manufacturing technologies, and the interrelationship between the production of silicon materials and their downstream industrial performance in the solar, chemical and aluminum fields.
20 years of experience in various global pyrometallurgical and silicon based industries as well as in solar and silicon manufacturing developments in Brasil, Venezuela, Saudi Arabia, Trinidad, China, Malaysia, Iceland, Russia, Oman, Algeria and the UAE.
The genius approach behind the PYR patents is to expose the feed material to the plasma 1 small granual at a time you dope, it paid of big time for them in their other products that have been scaled up very well, and is covered in many patents.
dont let the door hit you in the back on your way out.
