About
Hafnium Carbide HfC Powder:
Hafnium carbide HfC
This is a combination of carbon and hafnium.
Hafnium carbide
melting point
The melting point of this binary compound is approximately 3900degC. It is also one of the most resistant. However, it is not resistant to oxidation and can oxidize at temperatures as low or as 430°C.
Hafnium carbide
The HfO2 is a hard, black-gray, and brittle material. 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 1900degC-2300degC. It can be used to form the crucible for melting oxide and other forms of oxide.
The improved spark plasmasintering (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.

It is simple.
Is Hafnium Carbide HfC Powder made?
You can prepare hafnium carbonide powder by reacting hafnium oxide and carbon at 1800-2500°C. In this case, it is necessary to take longer to get rid of all oxygen.
Hafnium carbonide is a dark gray, brittle liquid. This can be made by heating an alloy of elements or by reacting hafnium trioxide with methane at 2150°C. You can obtain sufficient amounts of hafnium tetrachloride or metal sponge in the production of zirconium at large scales for use in nuclear reactors. Industrially, you can make hafnium carbonide from hafnium oxide or metal sponges at between 1500 and 1700C. It contains almost all of the carbon theoretically required (6.30%degC), and as much as 0.1% free carbon (219). This hafnium-carbidide compound is not true stoichiometric, but it only contains a carbon solution at one interstitial point of the face-centered cubic lattice.
Hydrofluoric acid will dissolve carbonization, but it is inert at room temperatures. At 250-500degC, carbonization is exothermic with halogen to create hafnium Tetrahalide. It also forms hafnium Oxide with oxygen at 500degC. At higher temperatures, the hafnium carbonide will lose some carbon due to hydrogen.
Hafnium Carbide Uses:
Hafnium carbonide (HfC), which has the highest melting temperature of any binary alloy, has many high-temperature uses. HfC is a suitable candidate for extreme high temperature applications like rocket nozzles or scramjet components. You can use carbonization in hard coatings. This is often done using processes like plasma spraying. HfC structural can also be used to make high-temperature components and thermal insulation materials.
Hafnium carbonide (HfC), which has a melting point of 3890degC above, can be used as a refractory binary material. HfC or NBC may also be used in reactors as refractory materials. Ta4HfC5 mixed carbide has the highest melting temperature at 4215degC.
1. Hafnium carbide can also be added to cemented caride. This is widely used in the fields of mold making and cutting tools.
2. Hafnium carbonide can be used as rocket nozzle material.
3. Hafnium-carbid is used for nuclear reactor control rods. It’s an excellent metal to make nuclear reactor controlrods.
4. Used for making ultra-high-temperature ceramics
5.Reactant used to synthesize an organometallic hafnium-containing polymer
6.For coating.
