KBr is used mostly in IR Spectroscopy techniques because it do not absorbs moisture at room temperature as compared to NaCl.
More over it do not give its own peak.

Is potassium bromide IR active?
Potassium bromide has transparent crystals in the range 0,25-25 μm; KBr is used in infrared spectroscopy.
Why KBr using in IR?
KBr is transparent to IR radiation, most alkali halides are transparent in ir
Is potassium fluoride IR active?
Potassium fluoride isn't used in infrared spectroscopy.
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
Why in some cases nujol technique is used In IR spectroscopy and in some other cases rest of techniques Is there any specific reason which technique to use and when?
you use nujol when you have a solid and combining the solid with the nujol forms a toothpaste consistency which you can then perform a neat IR on.
What Solvents can damage KBr cell windows in IR-spectroscopy?
Easy - water.
