Electronic properties of rare-earth orthoferrites,RFeO3 (R=rare earths) with optimized perovskite-type structures have been investigated systemically using the first principles method with a plane wave basis set.

The effects of mixed rare-earth oxides and CaCO3 on microstructure in in-situ Mg2Si/A1-Si composite with different Mg contents were investigated by optical microscope.

The composite thin films, Ag-La_2O_3, Ag-Nd_2O_3, Ag-Sm_2O_3, Au-La_2O_3, Au-Nd_2O_3 and Au-Sm_2O_3, in which Ag/Au nanometer particles were embedded in rare-earth oxides, were deposited by vacuum evaporation.

Under high pressure and below 1600℃ ,the sintering products are mixture of Si3N4 and the polymorphs of the rare-earth oxides.
