锑炉渣玻璃陶瓷的研究

Study on Antimony Slag Glass-Ceramic

本文研究了锑炉渣玻璃陶瓷的组成、热处理工艺对其微晶化过程、结构与性能的影响,论述了Cr_2O_3、ZrO_2、P_2O_5及TiO_2四种氧化物晶核剂的微晶化作用机理,并测定了所研制的锑炉渣玻璃陶瓷的主要性能.研究表明,TiO_2为该玻璃陶瓷的最有效的晶核剂.当添加10%时,按本研究确定的原始玻璃配方及热处理工艺获得了一种熔制温度为1360～1380℃、易实现微晶化且材料性能好的锑炉渣玻璃陶瓷.该材料以硅灰石、榍石及钙斜长石为主晶相,配料中锑炉渣的用量高于50%.

In this paper, the composition of Sb slag glass - ceramic and the effect of heat treatment on its microcrystallization process. structure and properties are studied, the microcrystalling mechanism of four oxides (Cr2O3, ZrO2, P2O5 and TiO2) as germination agent is described, and the principal properties of Sb slag glass -ceramic thus formed are determined.The result shows that TiO2 is the most effective germination agent for this glass -ceramic. Using original glass composition with 10% TiO2 and heat treatment technology,a Sb slag glass -ceramic was formed at 1360~1380℃ which microcrystallized easily and had good properties. This material takes wollastonite, pictite and calcarious plagioclase as main crystalline phase with the addition of Sb slag more than 50% in minor ingredients.
