Barium Fluoride (BaF 2) Windows While barium fluoride windows are less resistant to water than calcium fluoride, BaF 2 windows are the most resistant optical fluoride to high-energy radiation, but feature lower UV transmittance. BaF 2 has a Knoop hardness of 82. Note: These optical windows are very sensitive to thermal shock. Barium fluoride is a fast scintillator and can be used to detect X-rays, gamma rays, or other high energy particles such as 511 keV gamma photons in Positron Emission Tomography (PET).

Recommendations for Using Fluoride to Prevent and Control Dental Caries in the United States Fluoride is the ionic form of the element fluorine, the 13th most abundant element in the earth's crust. Fluoride is negatively charged and combines with positive ions (e.g., calcium or sodium) to form stable compounds (e.g., calcium fluoride or sodium fluoride).

- Fluoride is added to public drinking water to prevent tooth decay. Children who do not drink fluorinated public water because their homes use water from a private well often take fluoride tablets to prevent tooth decay.odium fluoride contains 45% elemental fluoride. Monofluorophosphate contains 19% elemental fluoride. 1  To prevent tooth decay (dental caries): in the US, fluoride is added to city water to a concentration of 0.7 to 1.2 parts per million (ppm).

Contrast Materials Barium-sulfate is the most common contrast material taken by mouth, or orally. When iodine-based and barium-sulfate contrast materials are present in a specific area of the body, they block or limit the ability of x-rays to pass through.

Barium Chloride As an inexpensive, soluble salt of barium, Barium Chloride finds wide application in the laboratory. It is commonly used as a test for sulfate ion. In industry, Barium Chloride is mainly used in the purification of brine solution in caustic chlorine plants and also in the manufacture of heat treatment salts, case hardening of steel, in the manufacture of pigments, and in the manufacture of other barium salts. Barium Chloride is also used in fireworks to give a bright green color.

Barium Barium is a metal, but has no significant uses as such. A significant medical use of barium is to enhance x-ray images of the intestinal tract. Barium has a high atomic number and absorbs x-rays strongly. A thin paste of barium sulfate, BaSO 4, and water is is swallowed to coat the alimentary canal.This gives greater definition and contrast to the x-ray images of the tract.The low solubility of barium sulfate minimizes the toxic effects which might occur with other barium compounds.The mineral form of barium sulfate is called barite.his gives greater definition and contrast to the x-ray images of the tract.

Fluoride Fluoride, a naturally-occurring mineral, helps prevent cavities in children and adults by making the outer surface of your teeth (enamel) more resistant to the acid attacks that cause tooth decay.efore teeth break through the gums, the fluoride taken in from foods, beverages and dietary supplements makes tooth enamel (the hard surface of the tooth) stronger, making it easier to resist tooth decay.

Caesium fluoride Caesium fluoride (cesium fluoride in North America), is an ionic compound usually found as a hygroscopic white solid. It is more soluble and more readily dissociated than sodium fluoride or potassium fluoride.aesium fluoride is a useful base in organic chemistry, due the fact that fluoride ion is largely unreactive as a nucleophile. It is reported that CsF gives higher yields in Knoevenagel condensation reactions than KF or NaF.

Barium swallow Barium swallow is a dedicated test of the pharynx, oesophagus, and proximal stomach, and may be performed as a single or double contrast study. The study is often modified to suit the history and symptoms of the individual patient, but it is often useful to evaluate the entire pathway from the lips to the gastric fundus.
