摘要：
A study was made of the effect of the diameter of polystyrene balls and the pH of the suspension, with sulfite lye additions, on the rheological and structural-mechanical properties of the alumina suspensions and the properties of the heat-insulating articles. It was found that the optimum casting properties are possessed by suspensions of two casting ranges: pH equals 2. 5 (acid deflocculation) and pH equals 9. 5 (alkaline deflocculation). The optimum stabilizing additive is 2% sulfite lye. The tests established the possibility of making porous corundum articles with excellent properties by the casting method.
