RE:Almost perfect Electronic grade is around 9n. I doubt a metalurgical process would achieve that without help. However what most people do not realize is that we pretty much have 4n here with the other process he mentioned in the video and this is with a pilot plant. When they increase the size of the reactor to commercial it will also increase the purity so my guess is that when all is said and done we will be producing 6n to 7n with a commercial unit.
