沉淀硫酸钡在国内的现状和发展前景

来源:河南钡丰化工有限公司   时间:2019-04-03

沉淀硫酸钡表现为白色无定形粉末,化学式为BaSO4,分子量为233.39,CAS为NO.7727-43-7,国家标准:GB/T2889-82,15℃时相对密度为4.50,1580℃时达到熔点。沉淀硫酸钡的折射率(1.63~1.65)较高,莫氏硬度为3.0,溶解度为20℃时:0.00024g/100g水,能吸收有害射线。它几乎不溶于乙醇、水、酸和碱、有机溶剂,可以溶于沸腾热浓硫酸中。是唯一的且无毒的常见钡盐,在600℃时用碳可还原成硫化钡和二氧化碳。沉淀硫酸易于高锰酸钾、碳酸钙或金属硝酸盐制成混晶。

 结语:重晶石矿产资源在我国数量巨大,应当具有发展生产沉淀硫酸钡的先天优势。然后我们生产技术与国外先进技术相比,还有不小的差距,导致国内产品质量上和价格上都有一定差距。所以,通过提高产品的技术含量,可以增加企业的经济效益。也就能实现清洁文明发展与可持续发展。
