Formation mechanism of oxidic nanoparticles under dehydration of coprecipitated magnesium and iron hydroxides was studied. It was shown that magnesium-iron spinel starts to form at T=400°С and Р=500 atm. Depending on the phase formation size of spinel nanoparticles crystallites varies in range 4090 nm.

Keywords: hydrothermal synthesis, spinel, magnesium and iron layered double hydroxides, nanoparticles, non-autonomous phase, non-autonomous state of matter, X-ray analysis.
