High Purity Zirconium Diboride ZrB2 Powder CAS 12045-64-6. Zirconium boride is a chemical substance with the molecular formula ZrB2.
Features of Zirconium Diboride ZrB2 powder:
TiB2, ZrB2, HfB2, VB2, NbB, NbB2, TaB, TaB2, CrB2, Mo2B5, W2B5, Fe2B, FeB, CoB, Co2B, NiB, Ni2B, Ni2B, LaB6, UB4, UB2.
Zirconium diboride (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure.
ZrB2 is an ultra-high-temperature ceramic (UHTC) with a melting point of 3246 °C.
This along with its relatively low density of 6.09 g/cm3 (measured density may be higher due to hafnium impurities) and good high-temperature strength makes it a candidate for high-temperature aerospace applications such as hypersonic flight or rocket propulsion systems.
It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and hafnium diboride.
Applications of Zirconium Diboride ZrB2 Powder:
(1) zirconium diboride powder is used to produce materials for ceramics.
(2) zirconium diboride powder can be used as a neutron absorber.
(3) zirconium diboride powder can be used as an abrasion-resistant coating.
(4) zirconium diboride powder can be used as crucible lining and anticorrosive chemical equipment.
(5) zirconium diboride powder can be used as anti-oxidation compound material.
(6) zirconium diboride powder can be used as a refractory material, especially in the status of anticorrosion of molten metals.
(7) zirconium diboride powder can be used as a thermally enhanced additive.
(8) zirconium diboride powder can be used for high-temperature resistance.
(9) zirconium diboride powder can be used as a special type of dope against high temperature, corrosion, and oxidation.
Storage Condition of Zirconium Diboride ZrB2 Powder:
The damp reunion will affect ZrB2 powder dispersion performance and using effects, therefore, zirconium diboride ZrB2 powder should be sealed in vacuum packing and stored in a cool and dry room, the zirconium diboride ZrB2 powder can not be exposure to air.
In addition, the ZrB2 powder should be avoided under stress.
Packing & Shipping of Zirconium Diboride ZrB2 Powder:
We have many different kinds of packing which depend on the zirconium diboride ZrB2 powder quantity.
Zirconium diboride ZrB2 powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Zirconium diboride ZrB2 powder shipping: could be shipped out by sea, by air.
