在实践中发现,一定温度范围内,熔融玻璃的粘度和对Pt合金的接触角,二者与温度的关系是相似的,促使我们对此进行研究。研究用的无碱和中碱玻璃的成分列于表1.玻璃粘度η与温度T的关系示如图1, In practice, it has been found that the viscosity of molten glass and the contact angle of Pt alloy within a certain temperature range are similar to the temperature, prompting us to study on this. The compositions of the alkali-free and medium-alkali glasses studied are listed in Table 1. The relationship between the glass viscosity η and the temperature T is shown in Fig. 1,
