摘要
以溶胶-凝胶法制备纳米钛酸钡粉体,利用价廉的重晶石为主要原料制备钡源,有效地克服了传统方法因采用有机钡盐或有机钛而导致的生产成本过高的缺点:研究结果表明,该方法可制备出高纯钛酸钡粉体,制备过程中三废排放物中基本不含有害物质,并可从母液中回收质量较高的副产品硝酸铵,具有产品质量高,原料来源广泛、价格低廉、工艺环保、节能等特点.
The powder of nano-barium titanate is produced by sol-gel method. In this route, the inexpensive barite is a barium source, which effectively overcomes the shortcomings of high costs caused by the use of organic Barium salt or organic titanium. The results show that high purity barium titanate powder can be prepared and waste emissions in the process do not include harmful substances. In addition,by-product of high-quality ammonium nitrate can be recycled from the the mother liquor. It can be seen that this way possesses characteristics of products of high quality, extensive concrete raw material, low-cost, environmental protection and it is energy saving.
