氧化锌|玻璃级氧化锌|龙力牌直接法氧化锌|龙力化工质量保证
中文名称:直接法氧化锌
英文名称:Zinc oxide,Zinc white
别称:锌氧粉、锌白
分子式:ZnO
分子量:81.39
物化性质:氧化锌为白色六角晶系结晶或粉末。无味、无毒、质细腻。相对密度5.606。折射率2.008-2.029。熔点1975℃。溶于酸、氢氧化钠、氯化铵,不溶于水、乙醇和氨水。属两性氧化物。在空气中吸收二氧化碳和水生成碳酸锌,呈黄色。加热时变黄,冷却后恢复白色。不透过紫外线,遇硫化氢不变黒。
用 途:氧化锌应用于玻璃(玻璃板、玻璃瓶、其它玻璃制品)、陶瓷(陶瓷卫浴、腰线、内墙砖、抛光砖、卫生洁具、日用瓷、陶瓷碗、陶瓷杯、陶瓷盘、陶瓷餐具等等陶瓷制品)、颜料、电缆、橡胶、搪瓷、石油、化工等行业。
制 法:以锌土为原料,经特殊工艺处理而得的氧化锌。
标准:GB/T3494—1996
