Hafnium Carbide Powder
Hafnium carbide is often carbon-deficient and, therefore, its composition often expressed as HfCx (x = 0.5 to 1.0). It has a cubic crystalline structure (rock salt) at any value of x.
The hafnium carbide powder is obtained by reducing the hafnium oxide (IV) with coal 1800-2000 ° C requires a long processing time to remove all the oxygen. Alternatively, high purity HfC coatings can be obtained by vapor phase chemical deposition of a mixture of methane gas, hydrogen, and hafnium (IV) vaporized chloride. Because of the technical complexity and the high cost of the synthesis, HfC has a very limited use despite its favorable properties as high hardness and melting point properties.
The magnetic properties of paramagnetic HfCx change x ≤ 0.8 to diamagnetic in large x. an inverse behavior (day-paramagnetic passage to increase x) for Tacx, despite having the same observed HfCx crystalline structure. and photovoltaics.
