Why Hafnium Carbide Can Form Solid Solution with Many Compounds?


What is Hafnium Carbide?

Hafnium carbide

This gray solid needs to be stored at room temperature. Hafnium carbonide is capable of forming a solid solution when mixed with other compounds such as ZrC or TaC. As an example, HfC-4TaC’s composite carbide has two phases. The first phase is the eutectic form of hafnium carbid tantalum carbonide. The second phase is a needle-like phase of free graphite with a ratio of 50 to 1. This “nearly eutectic” hafnium carbid (HfC), product has high thermal stability and high melting points. You can use it as the throat material for a rocket tube. Hafnium carbide is usually made from hafnium oxide (HfO2), carbon and an inert- or reducing atmosphere. It is heated to 1900°C. Hafnium carbonide can be combined with many other compounds (such ZrC, TaC etc.). ).


Introduction to Hafnium


Hafnium is often found in nature alongside zirconium. Zirconium minerals that contain hafnium all include zirconium. Hafnium, zirconium and both are very similar. In stone, beryllium zircon may contain as much as 15% HfO2. Metamorphic zircon can also contain more than 5% HfO2. Both of these minerals do not have much reserves so they are rarely used in industry. Hafnium can be mainly extracted from zirconium. To avoid accidental combustion, sponge hafnium must be carefully removed from the crucible. You should break large pieces of sponge hafnium down into small, manageable pieces. These can be used to make consumable electrodes and then melt them into ingots. Sponge hafnium must be kept from spontaneous combustion by crushing. Further purification of sponge haffnium follows the same procedure as for titanium and zirconium using the iodide heat decomposition method. Zirconium has slightly different control conditions. Keep the sponge hafnium blocks in close proximity to the iodization tanks at 600. The temperature at the centre of the hot wire is 1600, which is much higher than the 1300 needed to create a zirconium “crystal rod”. Forging, extrusion and tube drawing are some of the steps involved in molding hafnium.


Hafnium carbide’s main uses


It is used primarily to produce control rods for nuclear power plants. Pure hafnium, which is a plastic material, can be processed at high temperatures and resists corrosion. It’s an important component of the atomic energy sector. Hafnium, which has a high thermal neutron capture cross section, is an ideal neutron absorber. This can also be used to protect atomic reactors and as a control rod. Hafnium can also be used to propel rockets. The cathode of Xray tubes can be made from it in the electrical sector. Hafnium and other alloys can be used for the protection of frontal layers on rocket nozzles as well as glide reentry airplanes. HfT alloys can also be used in the manufacture of tool steels or resistance materials. Hafnium, an additive element, is used in heat-resistant alloys like tungsten and molybdenum. HfC, due to its high hardness as well as melting point can be added to cemented carbides. 4TaC*HfC, the compound having the highest melting points, has a melting temperature of approximately 4215.


Hafnium Carbide: Price


Hafnium Carbide’s purity and particle size will impact the price. The purchase volume may also have an effect on the cost. Large quantities of smaller amounts will result in a lower price. On our official website, you can see the price for Hafnium Carbide.
