Researchers from the Brown University in the United States have just “designed” a new material capable of resisting extremely high temperatures, this new material needs over 4.126 celsius or 7.460 degrees Fahrenheit to melt.
To put this into perspective, this temperature is equal to two-thirds of the temperature of the surface of the sun or hotter than the core of the Earth.
This wonder material is made from hafnium, nitrogen and carbon, its creators state that it has the highest known melting point.
Experts were able to come up with the breakthrough material using powerful computer simulations. The new discovery was described in the Journal Physical Review B (Rapid Communications) and shows that the material, made with the right amount of hafnium, nitrogen, and carbon could withstand the heat from the Earth’s core.
“The advantage of starting with the computational approach is we can try lots of different combinations very cheaply and find ones that might be worth experimenting with in the lab,” said Axel van de Walle, associate professor of engineering and co-author of the study with postdoctoral researcher Qijun Hong. “Otherwise we’d just be shooting in the dark. Now we know we have something that’s worth a try.”
According to the statement of researchers: Our work could lead to high strength materials for a variety of uses, from coating for gas turbines to heat shields for aeronautics. The next step now is to synthesize the compound and subject it to the calculated temperatures to corroborate the materials integrity. Manufacturing the material with the same atomic structure achieved in the simulator is crucial to determine its usefulness for the future.
“Melting point is a really difficult prediction problem compared to what has been done before,” van de Walle said. “For the modeling community, I think that’s what is special about this.”
“Melting point isn’t the only property that’s important [in material applications],” he said. “You would need to consider things like mechanical properties and oxidation resistance and all sorts of other properties. So taking those things into account you may want to mix other things with this that might lower the melting point. But since you’re already starting so high, you have more leeway to adjust other properties. So I think this gives people an idea of what can be done.”
