三氧化二锑作为氯乙稀合成树脂的阻燃剂和陶瓷工业的防泡剂等已被广泛地使用。其中具有代表性的生产方法有下述两种:1.硫化锑氧化法;2.金属锑氧化法。第一种方法由于产生大量的有毒性气休二氧化硫,而需要大规模的脱硫装置,第二种方法则因锑的反应温度均在800℃以上,其产品不仅三氧化二锑成为斜方、等轴两种晶系的混合物质,且含有四氧化二锑,从而实用性能
Antimony trioxide as a vinyl chloride synthetic resin flame retardant and the ceramic industry, such as anti-foam agent has been widely used. The representative of the production methods are the following two kinds: 1. Antimony sulfide oxidation; 2. Metal antimony oxidation. The first method requires a large-scale desulfurization device due to a large amount of toxic gas off sulfur dioxide, the second method because the reaction temperature of antimony are above 800 ℃, the product of not only antimony trioxide becomes oblique, etc. Axis of the two crystal system of mixed material, and contains antimony tetroxide, which practical performance
