Theoretical density of al2o3
Webb29 nov. 2001 · The atomic and electronic structure and other structural properties of the metastable κ phase of Al2O3 have been investigated with a first-principles total-energy … WebbThe theoretical bulk density of Al2O3-60 wt% 3Y-ZrO2/MgO is about 5.25g/cm3. The ob served value, which is about 5.10g/cm3, agrees well with the theoretical one. Then the increase in the density with the amount of 3Y-ZrO2 is attributed to the presence of high-density 3Y-ZrO2 and little pore.
