| Abstract | ||
| Adding of alumina to porcelain improve the mechanical properties of the green and fired body. This improvement depend on the properties of the added alumina, such as surface area, morphology and the percentage of the alumina. Adding of alumina effected also the properties of porcelain slip viscosity , less grinding of alumina result in high slip viscosity. The increasing of grinding finesse of the alumina rise the rate of body formation. This investigation showed that the alkali content of the alumina and the crushing states have significant effects on the workability of the porcelain green body. | ||
