China's graphite industry, page-23

Are we crisscrossing here? I was wondering whether the Mr Riddle had made a visit? I thought that was what you were saying in a cryptic sort of way?

Regarding your earlier post, I'm also confused about some of the content. Mainly because you used the term "amorphous flake". Amorphous graphite is not Flake graphite. I like to keep the two separated for analytical purposes. Amorphous graphite is associated with graphitization from hydrocarbon deposits, mainly coal, and therefore has a much lower purity grade in its concentrate. Plus the analytical report you posted was for Chinese Flake and not amorphous, so that just confused me as well.

Theoretically, any carbon based mineral can be used to make the high grade high density graphite needed for nuclear grade if it passes the Boron Test. It is just a question of costs. It all needs to undergo a pyrolytic process to be used for nuclear. I think we are talking HOPG here. You know the stuff that has the same high density and mechanical properties no matter which plane, axis, or side we are talking about. That is were vein graphite has a massive advantage of course. You know it all comes down to costs. The higher the input product for making the nuclear grade graphite the lower the costs are for the output. Or something like that.

On another note, it is very interesting to read the high sulphur content of Chinese graphite. High sulphur content is a big problem for some important user needs like making cast iron and I do believe, for making spherical graphite! That is a discussion for another day. Although I'll leave you with this consideration. Spheroidal graphite requires less than 120ppm sulphur otherwise the graphite basal planes are adversely affected and the morphology doesn't allow spheroidal formation.
