A team of researchers at the University of Barcelona, the University of Iya (Colombia) and Ramon Lalli University (Spain) recorded An unexpected find in the Tridimita fragment – Polymorphic forms of silicon (Sio₂) – from the historical meteorite that died in Steinbach, Germany, in 1724.
The study was published in a scientific journal Materials of the National Academy of Sciences (PNAS) And reviewedTime ‘.
Mineral with “Invariant conduction”
According to the results, the meteorite sample maintains the ability to heat, even fever.
This contrasts with what happens in ground solids: In crystals, thermal conductivity usually decreases with heat, while in glasses it usually increases.
Researchers explained that in this case two heat transmission mechanisms are combined: one, similar to waves in crystals, and the other more disturbing, characteristic of glass.
Both processes are balanced, leading to “constant” conduction within the temperature range measured in the laboratory.
Possible technological application
The conclusion opens up the ability to use this type of material in industrial supplements requiring stable heat control, such as refractory coatings or high temperature processes.
Tridimita is not a new mineral: it has been discovered both in a ground volcanic environment and in the Martian specimens analyzed by space missions.
Previous studies have discovered this polymorph in Mars, which suggests that it can be formed in different planetary conditions.
Restrictions study
The scientific team specified that this behavior may not be automatically extrapoled into all three forms in three, Because the effect may vary depending on the temperature or structural changes in the mineral.
The study combined the physics of the first principles, the automatic learning, which is applied to the materials and experiments of the thermoreflexia, which made it possible to confirm both the maturity of the conduction and the explanation of its nuclear origin.
