South Korean researchers have succeeded in developing a material that does not oxidize even at high temperatures, so it may be suitable for harnessing the energy generated by thermal radiation.

Thermal radiation – or thermal radiation – is nothing but electromagnetic radiation emitted by the movement of charged particles in a substance hotter than absolute zero. During the movement of charged particles, heat is generated, which is then radiated from the material itself.

Scientists have long worked to harness this radiation as an energy source. Heat generated by facilities such as thermal power plants or factories can be reused, but this requires materials that can withstand high temperatures.

This is where a new material developed by engineers at the Korea Institute of Science and Technology can come into play Advanced sciencein It was submitted. It can withstand temperatures up to 1000°C and very strong UV rays.

When manufacturing refractory materials, experts traditionally use raw materials such as tungsten, nickel and titanium nitride. However, it oxidizes easily at high temperatures, so Korean researchers looked for another solution.

According to the study, a special laser technology was used to create an extremely thin layer of barium stannite oxide (LBSO) mixed with lanthanum. After testing this, they found that the temperature was 1000°C and 9 mW/cm2 He concludes that it can also withstand strong ultraviolet rays Interesting geometry.

The researchers found that when arranged in several layers, they can generate electricity from thermal radiation. Panels similar to those used in solar panels can be used for this purpose.

According to experts, this substance can help deal with climate change and the energy crisis. It is believed that thermal energy production can be expanded to a commercial scale with its help.
