梯温法测定超薄玻璃液相线温度影响因素研究

Influence Factors of Measurement of Liquidus Temperature of Glass by the Gradient Furnace Method

液相线温度是玻璃制造工艺的重要参数,对评估玻璃配方的稳定性至关重要。基于梯温法探究保温时间、样品形态及观察位置等因素对测量超薄无碱玻璃液相线温度精确性的影响。结果显示,保温时间为24 h,采用棒状样品,从玻璃样品内部观测到的玻璃液相线温度较为准确。该研究为精准测量玻璃液相线温度提供参考,进而为设计玻璃配方与工业生产提供技术支撑。

Liquidus temperature is an important parameter in glass manufacturing process and is essential for assessing the stability of glass formulations.Based on the gradient furnace method,the influences of thermal insulation time,sample shape and observation position on the accuracy of liquidus temperature measurement of ultra-thin alkali-free glass were explored.The results showed that the liquidus temperature of glass was more accurate when the insulation time was 24 hours,the sample form was rod,and the observation position was inside glass.This study can provide a reference for the determination of glass liquidus temperature,and then provide support for glass formula design and industrial production.
