Zirconium Diboride Nano Powder Description
Zirconium diboride Nano Powder (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is an ultra-high temperature ceramic 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. ZrB2 parts are usually hot pressed (pressure applied to the heated powder) and then machined to shape.
Sintering of ZrB2 is hindered by the material’s covalent nature and presence of surface oxides which increase grain coarsening before densification during sintering. Pressureless sintering of ZrB2 is possible with sintering additives such as boron carbide and carbon which react with the surface oxides to increase the driving force for sintering but mechanical properties are degraded compared to hot-pressed he extremely rapid heating rates can result in incomplete reactions between Zr and B, the formation of stable oxides of Zr, and the retention of porosity.
Stoichiometric reactions have also been carried out by reaction of attrition milled wearing materials by grinding Zr and B powder and then hot pressing at 600 °C for 6 h, and nanoscale particles have been obtained by reacting attrition milled Zr and B precursor crystallites 10 nm in size.
The reduction of ZrO2 and HfO2 to their respective diborides can also be achieved via metallothermic reduction. Inexpensive precursor materials are used and reacted according to the reaction.

Aluminum Diboride Powder RELATED INFORMATION
Aluminum boride is an ionic compound, with a hexagonal crystal structure.  Aluminum boride at an absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen, or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are simpler and more economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

Brief Description of Hafnium carbide powder HfC:Â
Hafnium carbide ( HfC) is a chemical compound of hafnium and carbon With a melting point of about 3900 °C it is one of the most refractory binary compounds known. However, it has low oxidation resistance, with the oxidation starting at temperatures as low as 430 °C Hafnium carbide is usually carbon deficient and therefore its composition is often expressed as HfCx (x = 0.5 to 1.0). It has a cubic (rock-salt) crystal structure at any value of x Application of Hafnium carbide powder HfC:
- Used for preparation of ultra-high temperature ceramics
- The reactant in the synthesis of hafnium-containing organometallic polymers
- Used as an additive in alloys
- Used in coatings
- Widely used in microelectronics, semiconductor, aerospace high-temperature resistant material, coating materials, ceramic materials, ceramic target material, etc.

Niobium Boride Powder Related Information
Niobium boride powders having NbB, NbB2 and Nb3B4 phases in various amounts and single phase NbB powders were successfully synthesized by using powder metallurgy methods from related metal oxide raw materials in the presence of a strong reducing agent. Nb2O5, B2O3 and Mg powder blends were milled at room temperature
A high-energy ball mill for different time. Subsequently, an undesired MgO phase was removed from the milled powders by HCl leaching to constitute NbB–NbB2–Nb3B4 as final products, and they were subjected to an annealing process at 1500 °C for 4 h to observe probable boride transformation. Characterization was carried out by XRD, DSC, PSA, SEM/EDX, TEM, and VSM. The effects of milling time (up to 9 h) on the formation, microstructure, and thermal behavior of the final products were investigated.
The reduction reaction took place after milling stoichiometric powder blends for 2 h. Nano-sized NbB–NbB2–Nb3B4 powders in high purity were obtained in the absence of any secondary phase and any impurity via mechanochemistry by milling for 5 h and leaching with 4 mol/L HCl. After annealing, pure and nano-sized NbB–NbB2–Nb3B4 powders transformed into a single NbB phase without leaving behind NbB2 and Nb3B4 phases.
