High pressure high temperature synthesis has proved a fruitful route to new materials. Though an inherently powerful technique the amount of sample produced is often limited to a few mm3. As part of our ongoing program in this area we have isolated several new phases where neutron diffraction would add significantly to our understanding but which are available only in small quantities. We aim to investigate Sc1.80Mn1.53Ni0.67O6 to confirm the presence of Mn on the A site and the degree of Mn/Ni on the B site as well as the incommensurately modulated perovskites BiCo½Ti½O3 and BiNi½Ti½O3, the former of which is weakly ferromagnetic bellow 40K and according to synchrotron refinements polar. Here neutron should show whether there is any B site order and will provide more accurate oxygen positions to confirm wether or not the material is polar.
