ABSTRACT

 Glass – ceramic material as main component in aerospace application ( shuttle ), biomaterial for the veneering of metal restoration in destroy. In this work glass-ceramic from raw material ( Oxides + BaO ) was prepared. The XRD analysis showed that the heat treatment causes a very rapid crystallization process and at 900 °C, a new phase, MgFe2O4 structure appears in the glass matrix. Addition of different weight percentage of Magnesium metal to glass – ceramic were studied to estimate some properties such as density , young modulus, and hardness. The results show decreasing in density to 2.06*103 when add 9%Mg , this result prefer in application of glass-ceramic, especially in aerospace application ( window of shuttle ). The addition of 9% Mg leads to increase young modulus ( E ) to ( 73.5 Gpa). Mg addition on glass-Ceramic leads to decrease Hardness to (260.5 HB at 9% Mg). Microstructure inspection show the gradually spread of Mg metal through the glass matrix leading to a consolidate for all the alternative properties.

Keywords: Addition of Mg , Glass ceramic, density , mechanical properties.
