Stable MgxZn1−xO solid solutions (0.32≤x≤0.67) with a rock salt structure were synthesized at temperatures higher than 700 °C and pressures above 5 GPa. The lattice parameters and the Mg/Zn ratio were determined by the Rietveld method from the

In an opposed-movement multianvil high-pressure device, the anvils slide against each other, inwards or outwards, without any extrudable gasket. In this device, accurate controlled support pressures can be applied on each flank of all the anvils. A f

The structure of the cristobalite-like polymorph of phosphorus oxynitride PON has been refined using neutron powder diffraction data. It is tetragonal, space group I&4macr;2d, Z=4. The four P–(O,N) distances are equal but the tetrahedron is compres
