Barium fluoride lenses can be used as spherical lenses with different appearances, such as planoconvex lens (PCX), meniscus lens (MSC), biconvex lens (BCX), and can be made into various sizes. Barium fluoride (BaF 2) is a very hard material, but it is very sensitive to thermal shock. Our company has a complete production and assembly line of barium fluoride lenses, and has the capacity of batch supply. In addition to customized ingredients and new proprietary technologies for commercial and research applications, we can also produce materials that meet customized specifications as required. Provide typical and customized packaging, as well as other research, technology and safety (MSDS) data. Please contact us for the above delivery time and price information.
Barium (atomic symbol: Ba, atomic number: 56) is an element of group S, group 2 and group 6 with atomic number 137.27. The number of electrons in each barium shell is [2, 8, 18, 18, 8, 2], and its electronic configuration is [Xe] 6s 2. Barium Bohr model Barium is a kind of alkaline earth metal. The radius of the barium atom is 222 pm, and the van der Waals radius is 268 pm. Barium was discovered by Carl Wilhelm Scheele in 1772 and separated by Humphry Davy in 1808. The elemental form of barium is a soft silver-gray metal. Industrial applications for barium include as a “getter”, or unwanted gas remover, for vacuum tubes, and as an additive for steel and cast iron. Barium is also used as bearing alloy with silicon and aluminum. The main commercial source of barium is the mineral barite (BaSO 4), which is not a naturally occurring free element. The name of barium comes from the Greek “barys”, meaning heavy.
Fluorine is the element of block P, group 17, period 2. Its electronic configuration is [He] 2s 22p 5. The covalent radius of fluorine atom is 64 pm, and the van der Waals radius is 135 pm. Fluorine has a light yellow appearance in its elemental form (CAS 7782-41-4). Fluorine was discovered by Andre é – Marie Amp è re in 1810. It was separated by Henri Moissan in 1886.
