Yttrium(III) fluoride Suppliers
Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula YF3. It
is not known naturally in 'pure' form. Its CAS. is 13709-49-4. MW is 145.90. It occurs as
a white powder.
Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films,
glasses and ceramics. Yttrium Fluoride is a water insoluble Yttrium source for use in
oxygen-sensitive applications, such as metal production. In extremely low concentrations
(ppm), fluoride compounds are used in health applications.
Fluoride compounds also have significant uses in synthetic organic chemistry. They are
commonly also used to alloy metal and for optical deposition. Certain fluoride compounds
can be produced at nanoscale and in ultra high purity forms. Yttrium has the highest
thermo-dynamic affinity for oxygen, useful in ceramics for crucibles for molten reactive
metals, in florescent phosphors, computer displays and automotive fuel sensors. Yttria
stabilized zirconia is used in high temperature applications and as an electrolyte in
fuel cells. Yttrium Fluoride is generally immediately available in most volumes.

Zirconium dioxide for Sale
Zirconium dioxide (ZrO2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Zirconia as a pure oxide does not occur in nature but it is found in baddeleyite and zircon (ZrSiO4) which form the main sources for the material. Of the two of these, zircon is by far the most widespread but it is less pure and requires a significant amount of processing to yield zirconia.
The processing of zirconia involves the separation and removal of undesirable materials and impurities - in the case of zircon - silica, and for baddeleyite, iron and titanium oxides. Pure zirconia exists in the monoclinic form at room temperature. Cubic and tetragonal phases are also stable at higher temperatures. Another low thermal conductivity use is a ceramic fiber insulation for crystal growth furnaces, fuel cell stack insulation and infrared heating systems. Thermodynamically the higher the operation temperature of an engine, the greater the possible efficiency (see Carnot heat engine).
Zirconium dioxide can occur as a white powder which possesses both acidic and basic properties.
On account of its infusibility and brilliant luminosity when incandescent, it was used as an ingredient of sticks for limelight. The cubic phase of zirconia also has a very low thermal conductivity, which has led to its use as a thermal barrier coating or TBC in jet and diesel engines to allow operation at higher temperatures. The transformation of monoclinic to cubic zirconia occurs at 800-1000°C and is accompanied by a large change in lattice size. A consequence of this phase change is a large volume expansion on cooling which make the fabrication of pure zirconia ceramics impossible.

Gadolinium(III) oxide is a chemical compound. It is used as phosphor and additives of magnetic materials, etc. It is one of the most commonly available forms of the rare earth element gadolinium, derivatives of which are potential contrast agents for magnetic resonance imaging.
There are two types of gadolinium sites in the cubic structure, both with a coordination number of 6 but with different geometry of the surrounding oxygen atoms. At room temperature, the cubic structure is the most stable and a phase change to the monoclinic structure takes place at 1200 °C. From 2100 °C and up to the melting point at 2420 °C, a hexagonal phase dominates. Several methods are known for the synthesis of gadolinium oxide nanoparticles, mostly based on precipitation of the hydroxide by the reaction of gadolinium ions with hydroxide, followed by thermal dehydration to the oxide.
