摘要
以氟铝酸盐玻璃、氟磷酸盐玻璃和BGGFO玻璃为研究对象 ,探讨了在进行DTA测量时的一些影响因素。根据研究结果 ,选用退火玻璃进行DTA测量有助于准确判定Tg 温度 ;DTA测量玻璃样品粒度应在 1～ 2 .5mm之间 ,可以获得较好的测量重复性 ;同时 。
Some factors influencing the results of DTA were investigated by using fluoroaluminate glass, fluorophosphate glass and BGGFO glass as the testing samples. The results show that the annealed glass samples give more accurate T g values, and the grain size of the glass samples within a range of 1～2.5mm shows better reproducibility. This paper also described the comparison amongst the indices of thermal shock resistance of some different glasses.
