Abstract
Earlier workers have reported various techniques of making alumina slips, and the main factors affecting slip characteristics are: particle size distribution, density and pH of the slip. Fluidity or viscosity of the slip is dependent on the density and pH. In this work, emphasis has been placed on mould porosity, and keeping particle size distribution and pH constant, experiments have been carried out to investigate into the following aspects: 1. Effect of mould porosity and slip density on dry density of castings. 2. Effect of slip density on casting rate. 3. Effect of slip density on its viscosity. 4. Effect of different ranges of the temperature product. All samples were drain cast in a specially designed mould. The maximum obtainable slip density was limited by the appearance of dilatancy, imparting high resistance to flow. The slip viscosity increased rapidly beyond this point. Dry density of castings increased with increasing mould porosity up to the point of appearance of dilatancy. No significant variation in dry density· was noticed on further increasing the slip density. Higher firing temperature eliminated the pores in relatively shorter time.
