摘要
运用XRD,SEM,DTA和化学分析等手段研究了不同冷却速度及添加剂对SiO2-Al2O3-CaO(MgO-Fe2O3-Na2O)系玻璃分相及性能的影响。结果发现不同冷却速度处理对玻璃的分相有明显影响,使玻璃呈不同颜色,其中冷却速度为15℃/min处理得到的玻璃其抗折强度高于600℃退火玻璃。TiO2的加入对分相影响显著。
The effects of different cooling rates and additives on the phase separation and properties of SiO_2Al_2O_3CaO(MgOFe_2O_3Na_2O) glass have been studied by means of DTA,SEM,XRD and chemical analysis,and it is found that the glass had obvious phase separation and various colours at different cooling rate,and the tensile strength of the glass phase separated at the cooling rate of 15℃/min is higher than that of the glass annealed at 600℃Additive TiO_2 has a remarkable effect on the phase separation of glass
