Products Description

Industrial silicon is the basic raw material of silicon alloy, organic silicon, and solar-grade silicon. It is widely used in national defense, aerospace, electronics, new energy and other industries. It plays an irreplaceable role in the national economy. Its annual output has reached more than 230 tons.

In order to meet the requirements of high-purity silicon products, industrial silicon needs to increase the process of blowing and refining. In this process, due to the introduction of oxygen, a large amount of silicon slag will be produced. During the process, 15-20% industrial silicon will be wrapped into the slag.

At present, silicon slag is mainly stored as waste slag for a long time, as a paving material or as a base material in the foundry industry, which has brought a series of environmental problems and caused a large loss of silicon resources, seriously affecting the economic benefits of enterprises. In order to realize the sustainable development of resources and environment, it is imminent to study the comprehensive utilization technology of silicon slag.

In recent years, industrial silicon enterprises and scholars have paid more and more attention to the research and application of silicon slag recycling technology. In the research, it was found that the silicon slag has complex phases, which contain silicon phases such as elemental silicon, silicon carbide, and silicate. At present, the detection of silicon is mainly for the analysis of the element content in industrial silicon.

The detection method of elemental silicon content in the compound.

Including x-ray fluorescence spectrometry (xrf) for determination of element content (14849.5-2014), inductively coupled plasma atomic emission spectrometry (ico-aes) for determination of element content (14849.4-2014) and infrared absorption method (ftir) for carbon Determination of content (14849.6-2014), etc.

The Japanese standard jisg2312-1986 and the American standard astma922-2005 also proposed analytical standards for the chemical composition of industrial silicon. The above chemical analysis standards for industrial silicon at home and abroad are all for the analysis of the impurity content in industrial silicon, but the test methods for the content of elemental silicon in the complex silicon phase (silicon slag) components are not involved. At present, the content of elemental silicon in silicon slag cannot be obtained by conventional methods such as xrd, xrf, and icp, but it has become a key issue restricting the development of research technology for industrial silicon recycling in silicon slag.
