摘要：

The influence of the high temperature reduction on the metal-support interaction in the Ni-SiO2 system was studied by TEM, selected area diffraction, micro- and nanodiffraction. The formation of the Ni3Si intermetallic compound was observed after prolonged heating at 850 K in a hydrogen atmosphere. Nano- and microdiffraction analysis showed that a fraction of the smaller Ni crystallites (≤ 5 nm) was fully converted into Ni3Si. Larger particles (> 10 nm) were often composed of Ni metal and Ni3Si intermetallic compound. © 1990 Elsevier Science Publishers B.V. (North-Holland).
