Glass is made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with a small amount of auxiliary raw materials added. Its main components are silica and other oxides. X-ray fluorescence spectroscopy (XRF) can simply and quickly analyze the composition and concentration of SiO2, Na2O, CaO, MgO, Al2O3, K2O, Fe2O3 and other components in glass samples.
Industrial silicon, also known as metallic silicon, is produced through high-temperature reduction reactions of silicon ore (main component is silica), charcoal, coal, petroleum coke and other carbonaceous reducing agents. Its impurities mainly include iron, aluminum, calcium, etc. According to the content of iron, aluminum and calcium, it can be divided into different grades. Common grades include 5530#, 5210#, 4410#, 4210#, 4110#, 3303#, 2202#, 1101#, etc. Industrial silicon has a special status in my country's economic and social development. It is an indispensable and important material for the development of new energy and new material industries, showing broad application prospects. As a fast and non-destructive element content detection method, XRF can help users quickly test the content of impurity elements in industrial silicon and distinguish grades.
The quality of raw limestone is one of the important determinants of the quality of the end product . The chemical composition of limestone not only affects the technical quality indicators of the product, but also has a great impact on the processing process of the limestone. Different fields have different requirements for the composition of limestone. Therefore, in order to ensure the consistency of end product quality and the safety of the process, it is necessary to continuously monitor the quality changes of limestone.
The traditional chemical sample detection process is cumbersome and requires the use of dangerous chemical reagents such as strong acids, and it is impossible to detect multiple elemental components at the same time. As an accurate and efficient analysis method, XRF can easily achieve simple, fast and accurate sample testing purposes, and plays a very important role in the quality testing of limestone.
Quartz sand is quartz particles obtained by crushing quartz stone. Quartz sand is an important industrial mineral raw material and a non-chemical hazardous material.
The main mineral component of quartz sand is SiO2. In addition to silicon dioxide, quartz sand often contains small amounts of impurities such as Al2O3, CaO, MgO, Na2O, K2O, Fe2O3, TiO2, and Cr2O3, etc., which will affect its chemical stability and use effect. It is an important indicator for testing the quality of quartz sand.
Chemical analysis method is one of the most widely used quartz sand composition detection methods at present. This method performs chemical analysis on quartz sand samples to obtain important parameters such as its composition and content data. Commonly used chemical analysis methods include spark spectrometry, X-ray fluorescence spectrometry, energy spectrometry, etc.
