摘要
根据石英砂的特点 ,通过对氢氟酸法和熔融法的对比试验选定了操作简单快速的氢氟酸法测定石英砂中二氧化硅的含量 ,并规定了该测定方法的测定原理。
On the basis of the characteristics of arenaceous quartz and the comparison test from results hydrofluoric acid method and the melting method, a simple and new method termed as the hydrofluoric acid (MHA) method for quick analysis of the silicon dioxide content in arenaceous quartz was established.The analysis principlie,analysis condition and the precision of the MHA were discussed.
