The effect of sintering temperature on the porosity and compressive strength of corundum
Porous corundum ceramic samples were sintered at various temperatures in the range of 1350–1550°C. The effect of the sintering temperature on the porosity rate and compressive strength of corundum samples were investigated. The porosity rates were of the order of 3.3–38% and the high-density sample...

| description | Porous corundum ceramic samples were sintered at various temperatures in the range of 1350–1550°C. The effect of the sintering temperature on the porosity rate and compressive strength of corundum samples were investigated. The porosity rates were of the order of 3.3–38% and the high-density sample was obtained at a relatively high temperature. However, an increase of compressive strength by more than 6 times was observed with the sintering temperature rise. The Young’s modulus increased remarkably from 40.49 to 302.15 GPa, which is related to the corresponding decrease of porosity rate. |
