摘要
采用热重-微分热重-差示扫描量热(TG-DTA-DSC)同步热分析方法,对低铝高硼硅玻璃(ABS)熔制过程中发生的理化反应进行研究。作为比较,对普通钠钙硅玻璃(NCS)的性能做了相应的研究。通过粘度测试分析发现,所制备的低铝高硼硅玻璃软化点接近800℃,具有极好的耐热性。其工作温度和熔化温度较NCS均有大幅提高,分别为1375～1160℃和1699℃。热膨胀曲线表明所制备的ABS具有非常低的热膨胀系数,α(20～300℃)=3.9×10-6K-1,具有优良的抗热震性。
The physical and chemical reactions in melting process of alumino-borosilicate glass （ABS） was investigated by TG-DTA-DSC simultaneous thermal analyze. The properties of Na-Ca-Si （NCS） glass were also investigated as a contrast. The analysis of viscosity revealed,the softening point temperature of alumino-borosilcate glass was close to 800℃,showed excellent heat resistance. Compared with NCS,its work temperature and melting temperature,1375-1160℃ and 1699℃,respectively,increased substantially. As shown on the curve of thermal expansion,ABS showed good thermal shock resistance,with pretty low coefficient of thermal expansion,α（20-300℃）=3.9×10-6K-1.
