A stone desert is born

The micrograph shows boron oxide nanocrystals (in the form of pilars) coming out from a zirconium oxide (3YTZP) matrix. The event occured after the oxidation of a boron nitride (BN) nanoplatelets/3YTZP composite at temperatures over 1000 ºC. We can also see that due to this oxidation, the 3YTZP grains on the surface have suffered a martensitic transformation from the tetragonal to the monoclinic phase (visible because of a higher grain size).
