Over controlled heat treatment, the glass based on sio2-mgo-al2o3-k2o-f system is converted to glass-ceramic containing the present work is concerned to demonstrate the effect of mo (m = ca, sr, and ba) addition substituting k2o on the crystallization characteristics, microstructure, and thermal. In this work the six composition of glazes from sio2-al2o3-cao-mgo-na2o-k2o system were examined the only variable is the ratio of the silicon oxideto alumina at a constant content of other components: mgo, cao, k2o, na2o, zno in order to determine the real phase composition of the. Tabulated properties are in good agreement with thermophysical data, as well as being consistent with the bulk of phase equilibrium data obtained in solubility studies, weight change experiments, and reversals involving both single and mixed volatile species.
Aluminum, calcium, & calcium / aluminum al2o3, cao, and cao/al2o3 vs fe2o3(t) + mgo the terrestrial rocks that plot with the martian meteorites are probably basalts, which have similar mineralogy to the martian basalts (but, see na2o & k2o.
