Description of Hafnium Carbide HfC Powder:

Hafnium carbide HfC This is a combination of hafnium, carbon, and other elements. Hafnium carbide melting point The melting point of this binary compound is approximately 3900°C. The oxidation resistance of the compound is low, and it can oxidize at temperatures as low as 430°C.

Hafnium carbide The HfO2 is a hard, black-gray, and brittle material. A high cross-section absorbs the thermal neutrons. Resistivity 8.8mohm*cm. Used in nuclear reactor control rods. Preparation involves heating oil soot with H2 under H2 at 1900°C-2300°C. It can be used to form the crucible for melting oxide and other forms of oxide.

The improved spark plasma sintering (SPS) device was used for ultrafine carbonized Ha powder by carbothermal reduction reactions of HfO2 at 1650°C. It has a particle size of 125nm with an oxygen content below 0.5%. Powder purity is greater than 99.9%, with Zr being the exception. It is 99.6% when powder contains Zr impurities. The low synthesis temperatures, the rapid heating/cooling rates, and the current influence of the improved SPS procedure reduce intermediate reactions. This also minimizes particle growth. New synthesis methods allow for the production of large amounts of HfC (>175 g/day). HfC ceramics of high relative densities (>96%) can be obtained by SPS sintering at 2300°C for 30 minutes.

Production Method of Hafnium Carbide HfC Powder:

Direct carbonization method:

The chromium powder and carbon black are mixed in a certain proportion and heated to high temperatures in an inert gas or vacuum for direct carbonization. The key to this method is to control temperature and time to obtain chromium carbide with excellent properties. At the same time, in order to prevent deflagration and explosion, the ratio of carbon and chromium and reaction conditions need to be strictly controlled. Direct carbonization is one of the main methods for preparing chromium carbide in industry.

Hydrogen carbide process:

The chromium powder is heated to a high temperature along with hydrogen and carbon black so that the chromium reacts with hydrogen and carbon. This method can obtain high-purity chromium carbide but requires the use of high-purity hydrogen, so the cost is higher. At the same time, in order to prevent hydrogen explosions and air pollution, corresponding safety measures and environmental protection measures need to be taken.

Chlorination reduction method:

The chromium salt solution is chlorinated to obtain chromium chloride gas, and then the reduction reaction with carbon at low temperature to produce chromium carbide. This method can obtain high-purity chromium carbide but requires the use of chlorinating agents and reducing agents, so the cost is higher. At the same time, in order to prevent chlorine gas leakage and air pollution, corresponding safety measures and environmental protection measures need to be taken.

Chemical vapor deposition method:

At high temperatures, chromium compounds and carbide raw materials are deposited on the substrate by chemical reaction to produce chromium carbide coating. This method can produce high purity, high density, and uniform structure of chromium carbide coating but requires the use of a high-temperature furnace and other equipment, so the cost is high.

Mechanical alloying method:

Chromium carbide powder is obtained by mixing chromium powder and carbon black in a certain proportion and then ball milling at high temperatures for a certain time by mechanical alloying. This method can obtain high-purity chromium carbide powder but requires the use of a high-temperature furnace and other equipment, so the cost is high.
