Abstract
Section titled âAbstractâAbstractIn this study, the content and calculation equations of each substance in diamond wire saw silicon powder (DWSSP) were determined. Initially, the presence of amorphous SiO2 was proven by crystal transformation. Then, the SiO2 content was determined by SiO2-CaO phase diagram analysis, and the SiOx content was determined by using the oxygen conservation rule. The variation trend between the SiO2, SiOx, and Si contents and the O content was determined, according to the calculated SiO2 and SiOx content. In addition, linear fitting was performed on the SiO2, SiOx, and Si contents of five DWSSP raw materials, and a calculation equation for SiO2, SiOx, and Si was obtained through the total O content. The three-layer structure of DWSSP was revealed, the DWSSP consisting of a Si core, an intermediate SiOx layer, and a SiO2 shell. This study can accurately identify the content of SiO2, SiOx, and Si in DWSSP based on the detected oxygen content, and provide a better theoretical basis for the process selection and design for silicon recovery or high value materials preparation.Keywords: Diamond wire saw silicon powdercomposition and structurephase diagram analysisoxygen conservation ruleoxygen content Informed consentAll authors and associated personnel are aware of and agree to the content of this submission.Authorsâ contributionsTian Zhang: Methodology, Investigation, Experiment, Writing - original draft.Kuixian Wei: Resources, Writing - review & editing, Supervision.Shicong Yang: Conceptualization, Resources, Data curation, Writing - review & editing.Wenhui Ma: Supervision, Project administration, Funding acquisition.Conflict of interest statementThe authors declare that they have no financial or personal relationships with other people or organizations that may have inappropriately influenced this work.
