| Abstract | ||
| This research investigates manufacturing of Porcelain samples by using Dwekhla Kaolin, Arduma glass sand, Potassium Feldspar in addition to add some Alumina. Alumina is considered as one of the most significant components that can be used to improve the physical properties of ceramic components which is the main aim of this study. Samples have been formed by using semi dry compressing then, they have been sintered at 1300 oC. The study shows that by adding Alumina the Porcelain product properties have improved up 18% of the added Alumina percentage. By increasing the percentage more than 18%, as the study shows, the product properties began to drop, because Alumina forms feldspar liquid phase, but increasing the amount of Alumina more than 18% leads to keep some of it (Alumina) un melted , because it needs a high sintering temperature | ||
