Global hafnium carbide powder market trend 2024-2028 What is Hafnium Carbide HfC Used For? by Newsmannyslaysall

Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles.  Russia said it would resume gas supplies after it agreed to pay for them in rubles.  

Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.  

Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles.  When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.  

Because of the ever-changing international situation, the supply and prices of international bulk hafnium carbide powder are still very uncertain.

Hafnium carbide (HfC) is a grayish black powder with a face-centered cubic structure. It has a very high melting point (3890), is known to have a high melting point among single compounds, and is a good material for the lining of metal melting crucibles with high melting point.
Hafnium carbide has high elastic coefficient, good electrical and thermal conductivity, small coefficient of thermal expansion and good impact resistance, so it is very suitable for rocket nozzle materials, and it is also an important cermet material.

What is Hafnium Carbide HfC Used For?
Hafnium carbide is a kind of ceramic material with high temperature resistance and oxidation resistance, which has the advantages of good electrothermal conductivity and low thermal expansion. Hafnium carbide is suitable for manufacturing rocket nozzles, wing front and other important components, mainly used in aerospace, industrial ceramics and other fields.
Hafnium carbide has high hardness, can be used as an additive of cemented carbide and can form solid solution with many compounds (such as ZrC, TaC, etc.). It has been widely used in the field of cutting tools and moulds.
Hafnium carbide has high elastic coefficient, good electrothermal conductivity, small thermal expansion coefficient and good impact resistance, so it is suitable for rocket nozzle material, can be used in the nose cone of rocket, and has important applications in aerospace field. It also has important applications in nozzles, high-temperature lining, arc or electrolysis electrodes.
Hafnium carbide has good solid phase stability and chemical corrosion resistance, so it has great potential for use in high temperature environment. In addition, the field emission performance of carbon nanotube cathode can be improved by evaporating HfC film on the surface of carbon nanotube cathode.
The ablation resistance of hafnium carbide can be improved by adding hafnium carbide to Chand C composite. Hafnium carbide has many excellent physical and chemical properties, which makes it widely used in high temperature materials.

How Hard is Hafnium Carbide HfC?
Hafnium carbide has high hardness (> 9 Mohs). However, due to the technical complexity and high cost of synthesis, the use of HfC is limited.

What is Hafnium and What is It Used For?
Hafnium is a glossy silver-gray transition metal. It was discovered in 1923 and is the penultimate element in the periodic table with a stable nucleus (the last one is rhenium in 1925). Hafnium is rarely dissociated in nature, but exists in most zirconium minerals at a concentration of up to 5%. In fact, hafnium is very similar to zirconium in chemistry, so it is very difficult to separate the two elements. Most commercial hafnium is produced as a by-product of zirconium refining.
Hafnium is the 45th most abundant element on earth, accounting for about 3.3 parts per million (ppm) of the earth's crust by weight. Hafnium is very corrosion resistant due to the formation of an oxide film on the exposed surface. In fact, it is not affected by water, air and all bases and acids except hydrogen fluoride.
Hafnium has remarkable corrosion resistance and excellent neutron absorbent and can be used in nuclear submarines and nuclear reactor control rods which is a key technology for maintaining fission reaction. The control rod keeps the fission chain reaction active, but also prevents its acceleration from getting out of control.
Hafnium is used in electronic equipment such as cathodes and capacitors, as well as ceramics, photographic flash and bulb filaments. It is used as a getter in a vacuum tube, a substance that binds to the tube and removes trace gases from the tube. Hafnium is usually alloyed with other metals such as titanium, iron, niobium and tantalum. For example, heat-resistant hafnium-niobium alloys are used in aerospace applications, such as space rocket engines.
