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 Al 2 O 3 or/and CeO 2 particles were added into a SiO 2 -Al 2 O 3 -ZnOCaO-ZrO 2 -TiO 2 based glass, and crystallization behavior, fracture strength, and thermal shock behavior were systematically evaluated. The results indicate that with the addition of Al 2 O 3 or/and CeO 2 particles of moderate amount, the unfavorable needle-like ZrSiO 4 , Zn 2 SiO 4 , and CaTiSiO 5 crystals were largely inhibited when annealed at 900 degrees C. Accordingly, fracture strength is maintained high after heating at high temperatures. The thermal shock resistance is also enhanced drastically. The additive Al 2 O 3 is thermodynamically favorable to react with the glass, forming particulate ZnAl 2 O 4 instead of precipitating the needle-like crystals of Zn 2 SiO 4 and CaTiSiO 5 ; while CeO 2 will combine with ZrO 2 to form a solid solution and promote the precipitation of primary crystal CaZrTi 2 O 7 that will not transform to ZrSiO 4 with prolonging thermal exposure.
