直接法氧化锌

氧化锌 英文名称：Zinc Oxide 中文别名:锌白; 锌白粉; 活性氧化锌; 一氧化锌; 纳米氧化锌;氧化锌脱硫剂T304; 氧化锌脱硫剂 CAS号：1314-13-2 分子式：ZnO 分子量：81.4084 性状：白色非晶状粉末，属六角晶系。无臭、无毒、无砂性、质细腻。密度5.606g/cm3，折射率2.0041,1800℃升华。着色力是碱式碳酸铅的2倍，遮盖力是二氧化太和硫化锌的一半。不溶于水及乙醇，溶于酸、氢氧化钠、氯化铵，属两性氧化物。高温加热时呈黄色，冷却后恢复白色。在潮湿空气中能吸收二氧化碳和水分渐渐变成碱式碳酸锌。也能被碳或一氧化碳还原为金属锌。 用途：供橡胶、油漆、搪瓷、玻璃、陶瓷及其它化学工业用。 质量指标(符合 GB/T3494-1996)
