High Purity Zirconium Diboride (ZrB2)

Zirconium Diboride Nanopowder Highly pure

Zirconium Diboride Nanopowder: (ZrB2) ceramics have a high melting point, high hardness, high electrical conductivity, excellent corrosion resistance against molten iron and slags, superb thermal shock resistance.

Zirconium Diboride Nanopowder: (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 one of the promising materials for high-temperature applications in several industrial sectors, such as foundry or refractory industries.

Zirconium Diboride Nanopowder: is wet by molten metals but is not attacked by them, making it a useful material for molten metal crucibles, thermowell tubes for steel refining, and in electrical devices: heaters and igniters.

Applications are also found in the aerospatial industry: hypersonic re-entry vehicles, leading edges, nose caps, rocket nozzle inserts, and air augmented propulsion systems components.

Zirconium Diboride Nanopowder: applications have been recently proposed in aerospace leading-edge parts on hypersonic re-entry spacecraft, rockets nozzle inserts, and air propulsion system compounds this material can be electrical discharge machined for its low electrical resistivity (~10u ohms m) tp produce complex-shaped parts.

Zirconium Diboride Nanopowder: Hypersonic flights, re-entry vehicles, and propulsion applications all require new materials that can perform in oxidizing or corrosive atmospheres at temperatures in excess of 2000°C and sometimes over the course of a long working life.

Ultra High-Temperature Ceramics (UHTCs) are good candidates to fulfill these requirements.

Within this family, the Zirconium Diboride and Hafnium Boride based composites are the most attractive.

Synthesis of sub-micro sized high purity zirconium diboride powder through carbothermal and borothermal reduction method.

Sub-micro-sized zirconium diboride (ZrB2) powders were successfully prepared via the boro/carbothermal reduction method using zirconium oxide and boron carbide as the primary raw materials.

The prepared mixtures were thermally reacted at 1250 °C for 1 h.

The optimized composition range containing the lowest oxide and carbide impurity, which was 0.14% of oxygen and 0.3% of carbon contents, was determined using crystallographic and elemental analysis.

Zirconium Boride Powder ZrB2 Powder

The particle size was reduced from 5 µm to 245 nm by the addition of B4C as a reductant within a composition range that maintained the highest purity.

The morphology changed from faceted to angular hexagonal bar-like with a simultaneous growth in particle size.

Changes in the particle structure were a result of the existing liquid B2O3 phase during the reaction.

The 245-nm particles contained 12.1% oxygen content and 16.2% oxygen content for the 5-μm particle in the circumstance in which limited oxides could be produced.
