Subject field(s)
  • Chemical Elements and Compounds

K2TaF7
formula, see observation
CONT

Infrared and Raman spectroscopic measurements on a series of quenched alkali metal fluoride(Flinak) melts containing tantalum and oxide have led to the development of new methods of oxide analysis, which have an important use in the field of molten fluoride chemistry. The tantalum concentration was maintained at 2. 7 mol %, with the oxide concentration varying from 0 to 5. 4 mol %, over 22 samples.... The frequency and relative intensities of the bands enable the assignment of Ta-F and Ta-0 bands for both fluorotantalate and oxofluorotantalate entities.

CONT

The water and tantalum solution from the extractor contains a fluotantalic acid solution, from which potassium fluotantalate (K-salt, K2TaF7) or tantalum pentoxide (Ta2O5) can be precipitated through the addition of either potassium fluoride, or ammonia.

Record 4 1998-06-22

English

Subject field(s)
  • Radio Transmission and Reception
DEF

The difference in frequency between successive radio or television channels.

OBS

In present methods of channel assignment, the channel spacing is equal to the "necessary bandwidth : plus an allowance for frequency instability, assuming identical transmissions.

French

Domaine(s)
  • Émission et réception radio
CONT

Dans les régions où l'on utilise généralement l'espacement de 100 kHz ou 200 kHz entre les voies, la tolérance de fréquence de la porteuse sera de (plus ou moins) 0,005 pour cent.

CONT

Les effets du brouillage dans une voie adjacente sont limités par l'écartement des voies (c'est-à-dire des fréquences) et par la bande passante des récepteurs.
