Developing a Direct Synthetic Process from Raw Silicon Materials to Organic Silicon Compounds using Sand and Ash

-Making a Reduction in Cost and Energy Required for the Manufacturing of Silicon Products Possible-
October  25,2016
New Energy and Industrial Technology Development Organization (NEDO)

As part of a NEDO project, the National Institute of Advanced Industrial Science and Technology (AIST) and COLCOAT CO., LTD, have developed a highly efficient process for synthetizing tetraalkoxysilane in a small period of time using sand, ash, industrial byproducts, and other silica-containing compounds as a source of silicon that undergo a direct reaction with alcohol in the presence of inorganic dehydrating agent without the silicon needing to be converted to metallic silicon. AIST and COLCOAT CO., LTD, previously succeeded in developing the efficient generation of tetraalkoxysilane by exposing silica to a direct reaction with alcohol in the presence of an organic dehydrating agent, carbon dioxide, and small amounts of catalysts.

The present process could enable the effective utilization of resources as well as a reduction of the cost and energy required in the process of manufacturing of automotive parts, solar power equipment parts and materials, cosmetic ingredients, and silicon-based chemicals such as oils.
