A Method of Measuring Trace Amount Silicon in the New Synthetic Material Calcium Tungstate and Calcium Titanate

The silicon-molybdenum blue spectrophotometry was used to measure micro silicon in calcium tungstate and calcium titanale. The experiments were carried out to separate large quantities of interference elements of tungsten and titanium,and to analyse the factors influencing the silicon measurement. The measurement conditions were determined. The method is simple,convenient and accurate,and can be well repealed.
