Zirconium Nitride(ZrN) is an inorganic compound with a variety of crystal structures andchanges with composition.

Zirconium carbide can be fabricated in several ways. One method is carbothermic reaction of zirconia by graphite. This results in a powder. Densified ZrC can then be made by sintering the powder of ZrC at upwards of2000 °C. Hot pressing of

Zirconium compounds has been widely attention over the last decades due to itsexcellent physical and chemical properties.

HfB2 and ZrB2 are of interest for thermal protection materials because of favorable thermal stability, mechanical properties, and oxidation resistance. We have made dense diboride ceramics with 2 to 20 % SiC by hot pressing at 2000C and 500

Hafnium carbide and hafnium diboride melt at 3950 and 3250C, respectively. In an oxygen atmosphere, both form hafnium dioxide, which melts at about 2900C.

Titanium carbide(TiC) is a model structural material due to its hardness,hight-emperature stability, and lowdensity. However,the widespread use of TiC in cutting tools and other applications has been limited because the production of TiC

Transverse rupture tests were conducted on single-phase hafnium carbide and hafnium carbide containing 13-volume- percent hafnium diboride as a distinct second phase. These tests were performed between room temperature and 4755°F (2625°c).

Hafnium carbide (HfC) is a compound of carbon and hafnium.Its melting point is about 3900°C,which is one of the most refractory binary compounds known.However, its oxidation resistance is very low,and oxidation starts at temperatures as low

Titanium nitride (TiN), as a new type of multifunctional cermet material, has excellent characteristics such as high melting point, high hardness, wear resistance, good chemical stability, good electrical and thermal conductivity and optical

Hafnium alloy contains metal element hafnium, which is the substance with the highest melting point in the world today. The substance with the highest known melting point is a compound of hafnium: tetratantalum hafnium pentacarbide (Ta4HfC5)
