以铁矿渣为原料制备棕色玻璃

Preparation of brown glasses using iron slag as raw material

以铁矿渣、纯碱和硅石粉为主要原料,NaNO3和萤石作为助溶剂,Mn2O3为辅助着色剂熔制棕色玻璃。研究了不同铁锰配比对玻璃的颜色、热膨胀系数、化学稳定性、透光率及显微硬度的影响。加入适量的Mn2O3可以增强玻璃网络结构,使玻璃获得很好的化学稳定性。其中,当Mn2O3的质量分数达到4.32%时玻璃样品表现出更好的棕色效果。

The brown glasses was prepared by using iron-ore slag mix with soda,silica sand was used as the main raw material,NaNO3 and fluorite as a cosolvent,Mn2O3 as an auxiliary colorant.The ratio of iron and manganese impacts on chemical stability,transmittance,and the micro-hardness were studied.An appropriate amount of Mn2O3 can enhance the glass network structure of the glass,and get a good chemical stability.The glass sample massed the 4.32% Mn2O3 has the better color of brown.
