註釋This summary report presents the progress completed on the investigation of the mixing and sintering characteristics of Al2O3 and MgO particles. Separate inter-related areas of research were investigated which include particle preparation, dry and wet mixing, and the sintering behavior of Al2O and MgO. The techniques of particle reduction and analysis of particle size distribution were investigated by determining the variables which affect the resulting particles. Emphasis has been placed on control conditions for a jet pulverizer. Variables encountered in the dry mixing operation were found to be the mixer design, loading methods, and sampling methods. Analysis of these variables has been made by determining the standard deviation from a statistical number of samples. Surface properties of Al2O3 and MgO in aqueous media were investigated in order to understand wet mixing behavior. The basic mechanisms and the characteristics of the reaction between MgO and Al2O3 were studied with single crystals. The understanding of the fundamentals of the reaction enabled the establishment of optimum sintering conditions. Some of the properties of sintered compacts due to varied sintering conditions have been determined.
