Tenders invited for Supply and warranty of barium fluoride
The most common used for industrial thermography are calcium and barium fluoride, sapphire and IR transmissible polymer.
Calcium and barium fluoride are crystals which by their very nature, are fragile.
Our experiments showed that barium fluoride and silver iodide particles may be used as new stationary phases for TLC/FTIR analysis.

Paton Electric Welding Institute, show that the flux for ESR of titanium can consist of special purity refractory fluorides of alkali-earth metals: calcium fluoride, strontium fluoride and barium fluoride
, and also the fluorides of rare-earth metals (FREM) based on La[F.sub.4].
Shirley, Intrinsic birefringence in calcium fluoride and barium fluoride
The wavelengths are characteristic of molecular fluorine lasers and have to be focused by special materials, such as calcium fluoride and barium fluoride
. But the index of refraction varies rapidly with wavelength.

(Baf2) Purity:99.99% Or Better
NIST scientists are attempting to nullify the birefringence by using mixed crystals of calcium fluoride and barium fluoride
, a substance that exhibits opposite birefringence behavior.

These meas-urements were carried out on calcium fluoride and barium fluoride
using a combination of a unique ultra-violet polarimetry system and a unique ultraviolet Twyman-Green interferometer that was developed at NIST.
