Material specification

GfE Vanadium Pentoxide, high purity grade

Also known as GfE article no. 2008 582

The same producer's higher grade of the same compound. It is not simply a tighter version of the chemically pure grade: the producer names DIFFERENT applications for it, so the grade carries a statement about use and not only about purity.

What Lithoen records

Each claim states how it is known and cites its evidence.

EstablishedMIN V2O5 99.9 wt%; MAX V2O4 0.6; MAX Na 0.01; MAX K 0.01; MAX Fe 0.01; MAX particle size 1 mm.

Reported for this deposit

The high purity grade requires V2O5 at 99.9 weight per cent or more and caps V2O4 at 0.6 per cent with sodium, potassium and iron at 0.01 each, at the same particle size as the chemically pure grade.

EstablishedSite attribution: NOT ESTABLISHED. Place appearing on the product literature: Höfener Str. 45, 90431 Nürnberg — a contact address. Strongest independent site statement found: a regulator's record of vanadium-extraction plants at that street, dated 19 May 2023, naming no product and no grade. Channels searched on 17 September 2026: producer product pages and a public German environmental-procedure register. Not recovered from those channels on that date; this is not a statement that no such document exists.

Reported for this deposit

No source read places this graded article at a production site. The producer's data sheet prints Höfener Str. 45, 90431 Nürnberg in a contact block, beside a telephone number, a named contact person and a website, and states nothing about where the article is made. The producer's own vanadium chemicals page names no production location for any of its vanadium products and refers only to «our production». A 2023 regulator record separately places plants for the extraction of vanadium at that same street, which establishes an activity at an installation and not the manufacture of this article there. The two facts are not joined by any document read, and joining them would be this corpus's inference rather than a source's statement.
