烧结块中SiO_2的测定——重量法

Determination of SiO_2 in the Sintered Block——Gravimetric Method

文章研究了烧结块中SiO2的测定,试样用盐酸、硝酸分解,加高氯酸和硫酸除碳及其它杂质后脱水,过滤后灼烧,称量,并重复灼烧至恒重。该方法准确、快速、简便,适用于工厂的生产实际分析。

This article studies the determination of SiO2 in the sintered block. The sample is decomposed with Hydrochloric Acid and Nitric Acid, to remove Carbon and other impurities with Sulfate and Perchlorate, then dehydrated, calcinated after filtration, weighed, and repeat to constant re - ignition. The method is accurate, rapid, simple and applicable to the actual production of the factory.
