Abstract
The compacts carried out in the form of pins (of diameter 18 mm x 5 mm) according to the process of the products sintered in the presence of an abundant vitreous phase. The mixture compressed uniaxialement cold consists of an abrasive powder in Al2O3 and a vitreous binder containing kaolin, feldspar plagioclase and quartz a. Among the constant parameters of grinding: compactive effort, the temperature of cooking, and duration period. The required characteristics are: porosity, lifespan and the proportion of the components.
