| Abstract: | The preparation of a low thermal expansion glass-ceramic by sintering in terms of adding Li_2O/Al_2O_3=1:1 mixture (ratio) in the Li_2O-Al_2O_3-SiO_2 system is studied. The major phases precipitated from samples are identified by means of DTA. XRD. Thermal expansion coefficients of various samples are measured. The mechanism of the solid state reaction occurring in sintering and the influences on thermal expansion properties with respect to the chemical composition and crystal composition are also discussed. |
