| الوصف: | The tinting phenomena of iron oxide contained glasses were studied from aspects of the electronic configuration, the iron ions coordination fields and the ions structure in glass. Several iron ion tinting forms at different redox or COD (chemical oxygen demand) conditions and their influential factors were given necessary explanations. The results reveal that the Fe3+−O−Fe2+ structure is the real tinting reason of iron involved glasses, whereas the Si4+−O−Fe3+ and Si4+−O−Fe2+ formulations modify the glass colours. Under oxidizing melting condition, the amount of 4/6-coordinated Fe3+ increases and makes the glass colour yellowish. Conversely, reducing melting condition makes the 6-coordinated Fe2+ increased and gives much blue tint to the glass. The conventional tank furnace melting the very strong reducing condition, which is of high COD glass batch, is not suitable. The high ratio of ferrous/ferric in glass can be obtained with a new refining technology which contains no or little amount of refining agent. |
