he Seventh World Round Table Conference on Sintering, held in Herceg-Novi, Yugoslavia, Aug. 28 - Sept. 1, 1989. It was organized by the International Institute for the Science of Sintering (IISS), headquartered in Belgrade, Yugoslavia. Every fourth year since 1969, the Institute has organized such a

Progress in Preparation of ZnO Based Varistor Ceramics afterwards by adding ZnO..Various analytical methods such as optical and scanning electron microscopy, DTA, TGA, X-ray and EDAX were used in characterizing the powders and the resulting ceramics. Processes of formation of the main phases as well as their influence on resulting non-Ohmic behaviour, was investigated.

The Role of Powder Calcination Conditions in the Sintering Behaviour of Calcined ZrO2 Powdersragonal (mt) phase, have been rather extensively investigated, but they are still not completely understood (3–10). Besides, the relationship between powder processing and powder characteristics, as well as their influence on the densification behaviour and microstructure of sintered material seem to be of great importance.

Stereological Theory of Sinteringroperties of stereology to characterize the geometric state of the microstructure. The time evolution of these properties is related to the distribution of interface velocities on the pore-solid interface and the distribution of vacancy annihilation rates in grain boundaries through the geometricall

A New Model for Initial Sintering of Oxide Powders Under Controlled Gaseous Atmospherensity and mechanical toughness of the material. Applications of ultrafine oxide powders in the field of catalysis requires a good thermal stability. More often such materials do not exhibit the appropriate high surface area during a long period at temperatures in the range 800–1200 K. The decrease i

Mechanism of Anisotropic Dimensional Changes During Sintering of Metal Powder Compactring can be described quantitatively. The changes, however, are anisotropic in a cold pressed compact. The value depends on the direction in which it is measured, i.e., the compacting one or the lateral one.

Preparation of Well Defined Ceramic Powdersf the starting powders. Specifically, the temperature of sintering and the quality of the final products will depend on the size, shape, and uniformity of the original particles. As far as the chemical aspects are concerned, in addition to the obvious expectation that the bulk composition should be
