Intergranular films in Si3N4 studied by TEM

Abstract:

Like many ceramic materials, Si3N4 contains amorphous intergranular films (IGFs). These films affect or even dominate the properties of the ceramic material. As a result of the sintering process the amorphous IGFs in Si3N4 ceramics contain oxides of silicon and other elements. These additional elements are also observed in amorphous pockets where three or more grains meet. To obtain information about the local atomic structure of the IGFs we employ electron diffraction with a convergent probe...
