I worked in an area where 5 9s where just the start. We used 5 9s as the
expression for the purity of the metals that we sold as electronic
materials. The better stuff was 6 9s. Ther were a coule of elements that
were up to 7 or 8 9s but difficult. Some were considered 7 9s by the
industry as the impurities were such that they could be used as dopants in
the material. That is if you could not remove the bad stuff replace it
with good stuff.
7 9s arsenic that is 99.99999% pure. Great stuff.
