Discussion Overview

The discussion revolves around the functioning of oxygen pumps, specifically questioning the role of platinum electrodes and zirconia in the pumping process. Participants explore the mechanisms involved in oxygen ionization and the implications of terminology related to rare Earth elements.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires whether oxygen must pass through the platinum electrode to be pumped or if applying voltage to zirconia alone suffices.
  • Another participant points out a potential confusion regarding the classification of zirconium (Zr) as a rare Earth metal, suggesting that the terminology may mislead those unfamiliar with the concept.
  • A later reply clarifies that Zr is not a rare Earth element and expresses concern that the website's wording could confuse readers about the nature of rare Earth elements.
  • Further questions arise about the necessity of platinum for converting oxygen molecules to ions for pumping, indicating uncertainty about the process.

Areas of Agreement / Disagreement

Participants express differing views on the terminology related to rare Earth elements and the mechanics of oxygen pumping, with no consensus reached on the necessity of platinum in the process.

Contextual Notes

There is a lack of clarity regarding the definitions of oxygen molecules and oxygen anions, as well as the specific requirements for the pumping process, which remain unresolved.

lol the website says Zr is a rare Earth metal. That is such a confusing way to say Zr is rare.

I think you are confusing oxygen anion and oxygen molecules.
 
anything about my actual question please?

Nothing confusing here (and no, they don't mean it is rare).

https://en.wikipedia.org/wiki/Rare_earth_element
My research is Rare Earths so don't worry, I know these stuff.

I meant that Zr is not rare Earth elements. However, I suspected that most likely the author of the website meant that Zr is just simply an element that is rare, which I thought would cause confusion among those who don't know much about what "Rare Earth" really means.

what do you mean exactly?
It is not possible to pump oxygen molecules from a gas chamber?
Or platinum is required to convert them to ions and then to pump them?
 
anyone?
