| Abstract: | Glass-ceramics were prepared by sintering method on the basis of phase diagram.Microstructure and properties of the glass-ceramics were investigated by differential thermal analysis(DTA),X-ray diffraction(XRD),scanning electron microscope(SEM) observation,microhardness test.The results show that non porous glass-ceramics with main-crystal of wollastonite and diopside can be obtained in the sample sintered at 700 ℃ for 1 h and subsequently at 1100 ℃×1 h with the heating rate of 10 ℃/min. |
