| Abstract: | The metallurgical route from metallurgical grade silicon to solar grade silicon is being paid close attention on account of the advantages for lower cost and energy consumption and environmental friendly compared with the Siemens process.The status on the purification and preparation of solar grade silicon by metallurgical route in the world are reviewed and summarized.The investigative status and achievement for our group in hydrometallurgy,vacuum oxidizing refining,vacuum evaporation,vacuum degassing and vacuum directional solidification of metallurgical grade silicon are elaborated in detail.Some technical difficulties and key problems are therefore analyzed.Finally,the research and development directions for metallurgical route in future are put forward. |
| Keywords: | metallurgical route solar grade silicon purification vacuum |
