Determination of potassium fluoaluminate (potassium cryolite) content

Potassium cryolite, also known as potassium fluoaluminate, is specially made by chemical process.
Mainly used for brazing flux of aluminum, aluminum alloy, stainless steel and aluminum alloy smelting purification treatment of compound solvent composition, pesticides, industrial raw materials, ceramics, glass grinding wheel with additives of abrasive, etc.
According to the product standard (QB/dfd4294-2003), the content of each component of the potassium cryolite directly affects the quality of the product, and the production enterprise usually needs to measure it.
At present, the determination of F, Al, K, Na, Fe2O3, TiO2, MgO, CaO and SO4 in potassium cryolite is mainly based on the analysis method of cryolite.
These methods are cumbersome and long, and the analysis results are greatly affected by the analysis and reagent factors.
X-ray fluorescence spectra (XRF) method is widely used in the analysis of light element chemical products with its characteristics of sensitivity, simplicity and analysis of elements. The application of the analysis of fluoride composition is also applied.
The particle effect and the mineral effect were eliminated by the melting method.

Using artificial formulate appropriate calibration sample drawing the calibration curve, the optimize the instrument condition, on the basis of using X ray fluorescence spectrometry has been used to a batch icp-aes method, atomic absorption spectrometry and chemical legal value of the sample were analyzed, and a satisfied result is obtained.
