WebAluminium Oxide (Al2O3) or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications. Web6 - CTE of the porcelain and metal must be compatible so that. the veneering porcelain never undergoes tensile stresses, which would lead to cracking. PFM are therefore designed so that the CTE of the metal is slightly higher than that of the porcelain, thus placing the veneering porcelain in compression (where it is stronger) following cooling.
