What is Strontium fluoride

Strontium fluoride, SrF2, also called strontium difluoride and strontium(II) fluoride,
is a fluoride of strontium. Another proposal is that polarisation of the electron core
of the strontium atom creates an approximately tetrahedral distribution of charge that
interacts with the Sr-F bonds. It is a stable brittle white crystalline solid with
melting point of 1477°C and boiling point 2460°C. Strontium Fluoride has only
specialist applications. Optically, Strontium Fluoride has properties intermediate to
Calcium and Barium Fluoride.
The solid adopts the fluorite structure. In the vapour phase the SrF2 molecule is non
-linear with an F-Sr-F angle of approximately 120°. This is an exception to VSEPR
theory which would predict a linear structure. Ab initio calculations have been cited
to propose that contributions from d orbitals in the shell below the valence shell are
responsible.
Strontium fluoride is used as an optical material for a small range of special
applications, for example, as an optical coating on lenses and also as a
thermoluminescent dosimeter crystal. Another use is as a carrier of strontium-90
radioisotope in radioisotope thermoelectric generators.

How to Buy Chemical Compound

A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. A continuum of bond polarities exist between the purely covalent bond (as in H2) and ionic bonds. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds. In chemical compounds, the most common type of bond is a covalent bond, where both constituent atoms have similar electronegativity, resulting in an even sharing of electrons.
Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds. Individual oganisms form species populations (ant, human, deer, ponderosa pine, duckweed, etc.) which are further organized into complex communities composed of many species populations (chaparral, coastal sage scrub, yellow pine forest, redwood forest, etc.). Pure chemical elements are not considered chemical compounds, even if they consist of molecules which contain only multiple atoms of a single element (such as H2, S8, etc.), which are called diatomic molecules or polyatomic molecules.

what is yttrium used for

yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and it has often been classified as a "rare earth element". Arrhenius called the black mineral ytterbite after Ytterby. Bengt Geijer, the inspector of mines in Stockholm, carried out a rough analysis of ytterbite. It is always found combined with the lanthanides in rare earth minerals and is never found in nature as a free element. Its only stable isotope, 89Y, is also its only naturally occurring isotope. It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids. Shavings or turnings of the metal can ignite in air when they exceed 400 °C. When yttrium is finely divided it is very unstable in air.
Yttrium is a highly crystalline iron-gray, rare-earth metal. Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. The most important use of yttrium is in making phosphors, such as the red ones used in television set cathode ray tube (CRT) displays and in LEDs.
The largest use of the element is as its oxide yttria, Y2O3, which is used in making red phosphors for color television picture tubes. Yttrium metal has found some use alloyed in small amounts with other metals and It is used to increase the strength of aluminium and magnesium alloys.

At the Curie temperature, barium titanate undergoes a phase change from tetrahedral to cubic.
As a semiconductor it exhibits positive temperature of co-efficient of resistivity (PTCR) properties in the polycrystalline form. It is a ferroelectric ceramic material, with a photorefractive effect and piezoelectric properties. This means at a certain temperature, called the Curie temperature, the material will exhibit an increase in resistivity, the increase typically being several orders of magnitude. Barium titanate also exhibits ferroelectric properties and is an excellent photorefractive material.
