Crystallites of Nb 4 W 13 O 47 were heated by a focussed electron beam in an oxygen atmosphere (p O 2 = 20 mbar) inside the gas reaction cell installed within the polepiece of a 400 kilovolt transmission electron microscope. The HRTEM investigation of the resulting oxidation products revealed the pr
The direct confirmation of the existence of Cd-stabilized \(\boldsymbol{\beta}^{\prime \prime \prime}\) ferrite prepared as a stable phase in a \(\mathrm{K}_{2} \mathrm{O}-\mathrm{Fe}_{2} \mathrm{O}_{3}-\mathrm{CdO}\) system was done by high-resolution electron microscopy. It was confirmed that the
