What is Hafnium Carbide and Tantalum Carbide? Tantalum carbide is a brown powder of metal cubic crystals that belongs to the sodium chloride system. The tantalum carbide used today is a sintered cemented carbide grain growth inhibitor. This has an important effect in suppressing grain growth and has a densities of 14.3 g/cm3. It is insoluble and insoluble in water. It dissolves in a mixture of hydrofluoric, nitric and hydrofluoric acids. It is a strong antioxidant, and can be easily melted by potassium Pyrosulfate. It has a high resistance at 30 O and a conductivity of 60 O, which indicates that it is superconducting.

Hafnium carburide is normally synthesized by combining cerium (HfO2) and carbon with an inert, reducing or inert atmosphere. The reaction temperature ranges from 1900 to 2300 °C. This can lead to a solid-solution with many compounds such as ZrC and TaC. ).

Tantalum Hafnium Carbide properties:
Researchers have developed two new heat resistant materials, tantalum carbide (TaC), and tantalum carbonate (HaC), that can withstand temperatures of up to nearly 4,000 degrees C.

A research team from Imperial College London found that tantalum carbide's melting point has also set a new material record. These two materials are capable of withstanding temperatures up to 4000 deg C. They could be used for more extreme environments such as the insulation of the next-generation hypersonic spacecraft.

These two ceramics have excellent heat resistance. Due to their ability to resist extreme conditions, these materials could find applications in high-speed rockets and nuclear reactor fuel claddings that operate in extremely hot environments. It is not yet known if the two ceramics TaC and HfC can withstand extreme conditions. This is because there are currently no laboratory technologies that test the melting temperature of these two materials.

The researchers have developed a new technology for extreme heating that tests the heat resistance of TaC, HfC and mixtures. The researchers were able to determine, using this technique the melting point for both the TaC element and HfC mixture. The study has been published in Scientific Reports.

The melting points of both compounds are higher than those previously reported. TaC reaches 3768 deg C and HfC reaches 3958 deg C.

Researchers believe that the advent of these two materials could pave way for the next generation hypersonic planes. The future spacecraft could be faster than before.

The study was carried out by Dr. Omar Cedillos Barraza, while he was completing his Ph.D. at Imperial College London. Dr. Sadiez Barazza works as an assistant professor at the University of Texas at El Paso.

Saidi Barazza, a Dr. from the University of California at Berkeley, said that friction between an aircraft flying supersonic (more than Mach 5) and the surrounding air can cause a very high heat. TaC and HfC were not used up to now. Hypersonic vehicles. Our new discoveries show that the two materials are far more heat-resistant than previously believed. In fact, their heat resistance exceeds any other compound currently known to man. The fact that these materials are heat-resistant means they can be applied to new spacecraft. In the atmosphere, spacecrafts can fly at normal speeds and then supersonic speed in space. These two materials will make spacecraft able to withstand extreme heat generated in the shuttle atmosphere.

TaC or HfC could be used for the nose cap of the spacecraft, and the edge of any external instrument that is most likely to rub against the outside of the vehicle during flight.

At this time, manned spacecraft that are faster than 5 Mach cannot be flown. Saidi Barazza said, however that this dream could very well be realized in future.

Saidi Barazza continued: "Our tests have shown that these two materials are very promising for future spacecraft. These two materials are capable of withstanding extreme temperatures. If we could fly at Mach 5, then the flight from London to Sydney would only take 50 minutes. This would open up new opportunities for the whole world. A new continent, which brings new business opportunities."

Tantalum hafnium carbide uses:
Tantalum carburide is used as an additive in powder metalworking, fine ceramics (including cutting tools), chemical vapor deposition and tools for hard wear resistant alloys. The golden yellow color of the sintered tantalum carbide body can be used for watch ornaments.

Hafnium carbide is ideal for rocket nozzles. Also, it can be used to make a nose cone on reentry atmospheric rockets. It's used in ceramics, among other industries.
