固态Si颗粒在Na2O-CaO-SiO2多孔微晶玻璃中氧化的均匀性

Homogeneity of Solid Si Particle Oxidation in Na2O-CaO-SiO2 Porous Glass-ceramics

加入固态Si颗粒为Na2O-CaO-SiO2（NCS）多孔微晶玻璃配合料的气泡成核质点以调控孔结构,研究了固态Si颗粒在NCS配合料形成熔体过程中的氧化行为,用ANSYS模型模拟了NCS多孔微晶玻璃配合料的热场分布.结果表明,固态Si颗粒在NCS熔体形成过程中的氧化始于650℃,固态Si颗粒具有促进NCS配合料热场均匀分布的作用,且在NCS熔体形成过程中氧化程度相同,氧化过程不会影响NCS多孔微晶玻璃孔径分布的均匀性.

Addition solid Si particle as bubbe nucleation spots to adjust the pore structure of Na2O-CaO-SiO2（NCS） porous glass-ceramics, the oxidation behavior of Si in NCS porous glass-ceramics was studied, its effect on the thermal field distribution of NCS porous glass-ceramics was simulated by ANSYS model. The results showed that the oxidation of solid Si particle started at 650 ℃ in NCS porous glass-ceramics, and the thermal field distribution of NCS porous glass-ceramics gets uniform with the addition of solid Si particle, so that the oxidation degree of solid Si particle in NCS porous glass-ceramics are same, it won￠t affect the pore size distribution of NCS porous glass-ceramics.
