Y-doped alumina was sintered at 1500°C for 10 h under ultra-clean experimental conditions without experiencing any abnormal grain growth. The yttrium was fairly homogeneously distributed at the grain boundaries, with a mean value of Y = 5.5 at nm−

This review outlines the essence of a progressive study on the glassy inter-granular film (IGF) in a model ceramic system, the low-CaO-doped HIPed high-purity Si3N4. This was initiated from the finding of a systematic variation of equilibrium IGF thi

This article reviews data on wetting and the work of adhesion in metal/oxide systems at high temperatures in terms of proposed mutual adsorption models. Favorable adsorption energies can induce changes, especially near the high- and low-p(O2) limits

The mechanical behavior of four rare earth (RE)-Mg-doped Si 3 N 4 ceramics (RE = La, Lu, Y, Yb) with varying grain-boundary adhesion has been examined with emphasis on materials containing La and Lu (which represent the extremes of RE ionic radius).

In certain ceramics like Si 3 N 4 , SiC, SrTiO 3 , Al 2 O 3 , etc., the grain boundary (GB) region can have an amorphous film of about 1–2 nm thickness. These intergranular glassy films (IGFs) are characterized by a nearly constant thickness which

The presence of 1–2 nm wide intergranular glassy films (IGFs) found in ceramics such as Si3N4 and SiC strongly influences the properties of the material, including its fracture and creep behaviour. It is therefore important to know the evolution of
