Hafnium Carbide Powder

Copper monosulphide is a chemical compound of copper and sulfur. It occurs naturally as the dark indigo blue mineral covellite. He is a moderate electricity driver. a colloidal black CuS is formed when hydrogen sulfide, H2S, is bubbled through Cu (II) salt solutions. It is one of a series of binary copper and sulfur compounds (see copper sulfide for an overview of this subject), and has attracted interest because of their potential uses in catalysis. With a melting point of about 3900 ° C, it is one of the most refractory known composite tracks. However, it has a low resistance to oxidation and oxidation starts at temperatures up to 430 ° C.
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.
