English

Subject field(s)
  • Mineralogy
CONT

Plagioclase feldspars.-The sodium feldspar albite... and the calcium feldspar anorthite... form an isomorphous series from pure albite at one end and pure anorthite at the other, the molecules being completely miscible with each other.

French

Domaine(s)
  • Minéralogie
CONT

Le comportement d'un mélange de minéraux lors d'une variation de température diffère selon le degré de similitude des réseaux cristallins. [...] Les mélanges où les réseaux cristallins sont semblables. On parle alors de «séries isomorphes», et il arrive que les ions puissent être échangés sans altération de l'édifice. Ce sont de véritables solutions à l'état solide.

CONT

Les plagioclases [...] Ces minéraux sont décrits comme une solution solide : c'est une série isomorphe de l'albite à l'anorthite [...]

Record 5 2003-10-29

English

Subject field(s)
  • Chemical Elements and Compounds
CONT

Plagioclase is an amorphous series of albite, which is sodium aluminium silicate, and anorthite which is calcium aluminium silicate. It includes the gems sunstone and labradorite.

CONT

The following potential anti-caking agents have been identified for further investigation: calcium aluminum silicate, sodium aluminum silicate, iron ammonium citrate, tricalcium phosphate, stearates, calcium silicate, proprietary products such as Microsal ...

OBS

calcium aluminium silicate: a commercial name. The International Union of Pure and Applied Chemistry (IUPAC) recommends the form "aluminium" rather than "aluminum."

Record 6 1986-12-03

English

Subject field(s)
  • Astronomy
  • Planets
DEF

An achondritic stony meteorite composed essentially of calcic plagioclase and pigeonite. It has a higher content of iron and calcium than that of howardite. Eucrites were originally regarded to be anorthite-augite meteorites.

French

Domaine(s)
  • Astronomie
  • Planètes
CONT

D'autres achondrites sont pauvres en fer, nickel et magnésium; riches en calcium et aluminium: ce sont les angrites (...), les eucrites, à texture ophitique (clino-hypersthène, anorthite-bytownite) (...)

CONT

Les eucrites sont formées essentiellement de piégeonite et de feldspath calcique.
