Abstract

The object of the study is metallurgical silicon obtained from the «Tau-KenTemir» LLP plant, located in the Karaganda Region of the Republic of Kazakhstan. The problemthatneeds to be solvedin the framework of thisstudyisthehightechnologicalcomplexity, multi-stage natureandsignificantcost of traditionalprocesses for cleaningmetallurgicalsiliconfromrelatedchemicalimpurities.

An electrohydraulic unit was designed and assembled for the grinding of metallurgical silicon. The processing of metallurgical silicon was carried out with an increase in the discharge voltage of the storage device from 16 kV to 27 kV, the length of the interelectrode distance from 5mm to 11 mm, the capacitor capacity of 0.4 UF and the processing time of 5 min. Using the electrohydraulic method, particles of metallurgical silicon with an initial fraction of 3 mm, 5 mm and 10 mm were crushed to 0.074 mm. The results of crushing metallurgical silicon under the influence of the electrohydraulic method in a liquid medium allowed to determine the degree of grinding of the material.

Surface and quantitative analyses of powdered metallurgical silicon samples were performed using a scanning electron microscope and a Rigaku Simultix 15 spectrometer (Rigaku Corporation, produced in Japan).

The results obtained can be used in the study of the grinding characteristics of metallurgical silicon. High-purity silicon (polycrystalline and monocrystalline silicon) is widely used as a base material in the production of semiconductor devices and photovoltaic cells. It is also used in ferrous and non-ferrous metallurgy to produce alloys, as well as a raw material to produce high-purity silicon
