Hafnium carbonide (HfC), a grayish, black powder, has a face-centered cubic shape. It has a very low melting point (3890), which is why it is an excellent material to use as a lining for metal melting crucibles.

Hafnium carbonide is an important cermet material because of its high elastic coefficient, low coefficient of thermal expansion, good electrical conductivity, and high elastic coefficient.

What is Hafnium Carbide HfC used for?

Hafnium carbonide is a ceramic material that has high temperature resistance and resistance to oxidation. It also has the advantages of low thermal expansion, good electrothermal conductivity, and low thermal expansion. Hafnium carbid is used for the manufacture of rocket nozzles, wingfronts and other critical components. This material is mostly used in aerospace and industrial ceramics.

Hafnium carbide is hard, can be used to add cemented carbide, and can form solid solutions with many compounds (such ZrC or TaC). It is used extensively in the production of cutting tools and moulds.

Hafnium carbid has a high elastic coefficient, low thermal expansion coefficient, good electrothermal conductivity, and a small thermal conductivity. These properties make it suitable for rocket nozzle materials. It can also be used to make nozzles, high temperature linings, and arc or electrolysis electrons.

Hafnium carbid has excellent solid phase stability and chemical resistance. This makes it ideal for high-temperature environments. The field emission performance can also be improved by vaporizing HfC film on carbon nanotube catathode.

An addition of hafnium-carbid to Chand C can improve the hafnium-carbidide’s ablation resistance. Hafnium carbonide is widely used in high-temperature materials due to its excellent physical and chemical characteristics.

How hard is Hafnium-Carbide HfC?

Hafnium carbonide is hardy (> 9 Mohs). HfC can only be used in limited circumstances due to its high cost and technical complexity.

What is Hafnium, and How is it Used?

Hafnium can be described as a shiny, silver-gray, transition metal. It was first discovered in 1923. Hafnium is rarely dissociated in nature but can be found in zirconium mineral at concentrations up to 5%. Actually, hafnium and zirconium are very similar in chemistry so it is difficult to separate the elements. Most hafnium that is commercially available comes as a result of zirconium reprocessing.

Hafnium is earth’s 45th most abundant element. It accounts for about 3.3 parts in million (ppm), of earth’s crust. Hafnium can resist corrosion due to the formation an oxide film on its exposed surface. It is indestructible to water, air, bases, acids, except hydrogen fluoride, and it does not react with oxygen.

Hafnium’s remarkable corrosion resistance and high neutron absorbency make it an ideal material for nuclear submarines and control rods for nuclear reactors. This is key technology in maintaining fission reaction. The control rod prevents the fission chain reaction from accelerating out of control and keeps it active.

Hafnium is used to make electronic equipment like capacitors and cathodes. It also makes ceramics, photographic flash, and bulb filaments. It can be used to bind to vacuum tubes and remove trace gases. Hafnium is often alloyed to other metals like iron, titanium and niobium. Examples include aerospace applications like space rocket engines, which use heat-resistant hafnium/niobium alloys.
