摘要
以Na2 O2 Na2 CO3在刚玉坩埚或Na2 CO3 K2 CO3 H3BO3在铂坩埚中熔样 ,盐酸酸化 ,用钼蓝光度法测定铬铁中 5 0 %以下的硅量 ,方法简单快速 。
In this paper a simple and rapid photometric method for the determination of silicon less than 5 0% in ferrochrome with molybdenum blue is presented Silicon is determined after melting the sample with sodium peroxide sodium carbonate in alumina crucible or with sodium carbonate potassium carbonate boric acid in platinum crucible and acidizing by hydrochloric acid The method is precise,accurate and with satisfactory results
