Certain systems of oxides, nitrides and carbides have been recognized as th
e basic components of advanced materials for applications such as engineeri
ng and electronic ceramics, catalysts, sensors, etc. under extreme environm
ents. An understanding of the basic atomic and electronic properties of the
se systems will benefit enormously the industrial development of new materi
als featuring tailored properties. We present an overview of neutron scatte
ring studies of the crystal phases, microstructure, phonon and magnetic exc
itations of key materials including rare-earth phosphates, phosphate glasse
s, nanostructured metal oxides, as well as silicon nitride and silicon carb
ide ceramics. A close collaboration among neutron scattering experimentatio
n, molecular-dynamics simulation and material synthesis is emphasized. (C)
