Abstract

In this research high pure aluminum metal with the following weight percent
(1,2,3,4,5) has been added to machinable glass-ceramic, after the preparation of the
samples by pressing then firing the effect of this addition on the density, hardness,
young modulus, and polishing and grinding time of the machinable glass-ceramic
have been studied. It has been found that the increasing in aluminum percent lead to
slightly increase in density while the hardness, young modulus, and polishing and
grinding time decreased.
