According to a study in KDP crystal growth and performance, it’s found that the impurity content of potassium dihydrogen phosphate crystal by batch production affects directly the growth rate and optical properties of the KDP crystal. Through research on a variety of materials production methods, it’s found that there’re seldom reports on impurity removing technology by physical methods. This project studied the key process parameters and control factors on the batch production of potassium dihydrogen phosphate raw material. By modification and adjusting the process parameters, the quality of KDP crystal materials is improved.
This article studies the long-term stability of Na、Mg、Cr、Mn、Fe、Co、Cd、Ba、Pb in the matrix effect of potassium dihydrogen phosphate tested on ICP-MS Model X-series II manufactured by ThermoFisher. The test result proves good long-term stability and reliable analysis of the instrument.
