Method for determination of potassium fluoaluminate (potassium cryolite) content.

Potassium cryolite, also known as potassium fluoroaluminate, is specially prepared 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 in potassium cryolite directly influences the quality of the product, and the production enterprise usually determines the product.
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 influenced by the analysis personnel and reagent factors.
X-ray fluorescence spectrometry (XRF) method is widely used in the analysis of light element chemical products with its sensitive, simple and analytical elements, and it is also applied in the study of the analysis of fluoride composition.
The particle effect and 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.
