摘　　要：以不同组成配方的K_(2)O-B_(2)O_(3)-Al_(2)O_(3)-SiO_(2)玻璃作为研究对象,分别采用高温旋转粘度计和热显微镜测试方法,结合MYEGA粘温计算拟合方程对玻璃的粘温性能进行了研究,通过对比发现,3组不同配方的玻璃样品,依据热显微镜中获得的样品的半球温度、摊平温度结合热膨胀得到的玻璃转变温度进行MYEGA方程拟合,所得到的玻璃粘温曲线与依据高温旋转粘度的测试数据结合玻璃转变温度进行玻璃粘温拟合的结果高度吻合,在玻璃特征温度点的偏差小于0.85%。因此,采用热显微镜结合MYEGA方程可以代替高温旋转粘度计作为玻璃粘温性能研究的一种新手段。Na_(2)O-B_(2)O_(3)-SiO_(2) glass with different composition formulas is taken as the research object, and the viscosity temperature properties of the glass are studied by using the high temperature rotational viscometer and thermal microscope test methods respectively, combined with the MYEGA glass viscosity temperature calculation fitting equation.By comparing the three groups of different formulations of glass samples, the two kinds of glass viscosity and temperature curves are highly consistent, one is fitted by MYEGA equation based on the hemisphere temperature and molten flat temperature of the sample obtained by thermal microscope test and the glass transition temperature obtained by thermal expansion, another is fitted by MYEGA equation according to the high temperature rotational viscosity test data.The deviation at the characteristic temperature point of glass is less than 0.85%.Therefore, the thermal microscope combined with MYEGA equation can replace the high temperature rotational viscometer as a new method to study the viscosity properties of glass.
