About Inorganic Borides compound material basic knowledge:

 

What about the purity of rare earth Boride ?

Explain for purity of Rare Earth Boridewhat is the purity of Rare Earth BorideWhats mean is “TREO”Whats means is the “RE/TREO”? TREO means Total content of Rare Earth Oxide, REO/TREO means this RE element's content in the Total content of Rare Earth Oxide; for example La2O3/TREO: 99.9%, TREO: 99%, means La2O3content is 99.9% in the total content of Rare Earth Oxide and Total content of Rare Earth Oxide is 99%.

 

Total content of Rare Earth Boride are include those elements, Total 16 elements. They are La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc, Y

RE = rare earth

REM = rare-earth Metals

REE = rare-earth elements

REO = rare-earth Oxide

REY = rare-earth elements and yttrium

LREE = light rare earth elements (Sc, La, Ce, Pr, Nd, Pm, Sm, Eu, and Gd; also known as the cerium group)

HREE = heavy rare earth elements (Y, Tb, Dy, Ho, Er, Tm, Yb, and Lu; also known as the yttrium group

 

The borides can be classified loosely as boron rich or metal rich, for example the compound YB66 at one extreme through to Nd2Fe14B at the other. The generally accepted definition is that if the ratio of boron atoms to metal atoms is 4:1 or more the compound is boron rich, if it is less, then it is metal rich.

LaB6 is an inert refractory compound, used in hot cathodes because of its low work function for emission of electrodes; YB66 crystals, grown by an indirect-heating floating zone method, are used as monochromators for low-energy synchrotron X-rays.

Crystals of the specific rare-earth boride YB66 are used as X-ray monochromators for selecting X-rays with certain energies (in the 1–2 keV range) out of synchrotron radiation. Other rare-earth borides may find application as thermoelectric materials, owing to their low thermal conductivity; the latter originates from their complex, "amorphous-like", crystal structure.

The transition metals tend to form metal rich borides. Metal-rich borides, as a group, are inert and have high melting temperature. Some are easily formed and this explains their use in making turbine blades, rocket nozzles, etc. Some examples include AlB2 and TiB2. Recent investigations into this class of borides have revealed a wealth of interesting properties such as super conductivity at 39 K in MgB2 and the ultra-incompressibility of OsB2 and ReB2.

 

Applications for those Inorganic Borides material:

The diversity of the crystal structures of rare-earth borides results in interesting physical properties and potential applications in thermopower generation.Thermal conductivity of boron icosahedra based compounds is low because of their complex crystal structure; this property is favored for thermoelectric materials. On the other hand, these compounds exhibit very low (variable range hopping type) p-type electrical conductivity. Increasing the conductivity is a key issue for thermoelectric applications of these borides.

 

YB6 is used as a soft-X-ray monochromator for dispersing 1-2 keV synchrotron radiation at some synchrotron radiation facilities.Contrary to thermoelectric applications, high thermal conductivity is desirable for synchrotron radiation monochromators. YB66 exhibits low, amorphous-like thermal conductivity. However, transition metal doping increases the thermal conductivity twice in YNb0.3B62 as compared to undoped YB6
