A general strategy towards improving the strength and thermal shock resistance of glass-ceramics through microstructure regulation
文献摘要：
Glass-ceramics are usually obtained through controlled crystallization.In this work,we propose a new strategy to add an appropriate amount of oxide particles to the parent glass to improve the performance of glass-ceramics.Different amounts of Al2O3 or/and CeO2 particles were added into a SiO2-Al203-ZnO-CaO-ZrO2-TiO2 based glass,and crystallization behavior,fracture strength,and thermal shock behavior were systematically evaluated.The results indicate that with the addition of Al2O3 or/and CeO2 particles of moderate amount,the unfavorable needle-like ZrSiO4,Zn2SiO4,and CaTiSiO5 crystals were largely in-hibited when annealed at 900℃.Accordingly,fracture strength is maintained high after heating at high temperatures.The thermal shock resistance is also enhanced drastically.The additive Al2O3 is thermo-dynamically favorable to react with the glass,forming particulate ZnAl2O4 instead of precipitating the needle-like crystals of Zn2SiO4 and CaTiSiO5;while CeO2 will combine with ZrO2 to form a solid solu-tion and promote the precipitation of primary crystal CaZrTi2O7 that will not transform to ZrSiO4 with prolonging thermal exposure.
