摘要
器皿玻璃和高白料玻璃中,铁是影响玻璃白度的主要元素之一。目前,常通过总铁(三价铁和二价铁)的测定来考核玻璃的白度。事实上二价铁的着色能力比三价铁要强得多。控制玻璃中亚铁的含量比控制总铁更有积极意义,特别是在目前原料供应紧张。
Based on the principle that different valence irons have different staining characteristics, continuous method of determining ferrous and total iron content in glass by colourimetric analysis was proposed to estimate the transparency of glass. This method. is suitable for soda-lime glass.
