Material specification

SMZ Niobium pentoxide, Марка ПЧ

Also known as Ниобия пентаоксид, Марка ПЧ

A FIRST-PARTY producer grade for niobium pentoxide, taken from the producer's own grade sheet on the producer's own domain. Every impurity figure is a guaranteed ceiling and the Nb2O5 figure a guaranteed floor. Its effective date is recorded as UNKNOWN because the document prints no date at all — the PDF's own file timestamp is a property of the file and is not read as the issuer's date. Stated application: niobium metal, alloys, FeNb and NiNb master alloys of vacuum purity, niobium carbide, niobium-oxide capacitor powders and high-temperature pigments; grade В also optical glass, piezo- and electroceramics, ferrites and semiconductors.

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

EstablishedSite attribution: NOT ESTABLISHED. Place printed: Соликамск, ул. Правды, 9 — a company address. Grades named on the page: ПЧ, ТС, В. Technical-conditions document number on the page: NONE. Universality of the printed limits: DENIED BY THE PRODUCER — the list and content of analysed impurities may change by agreement with the consumer. Channel searched on 17 September 2026: the producer's own product pages.

Reported for this deposit

The producer's page for chemically pure niobium pentoxide names the grades ПЧ, ТС and В, carries no ГОСТ or ТУ number and no numeric table, and names no production site: the only place printed is the company address «Соликамск, ул. Правды, 9». The page further states that, by agreement with the consumer, the list and the content of the analysed impurities may be changed, so the printed limits of these grades are a starting point for negotiation rather than a universal guarantee.
