Method for selecting silicon metalloid in the direct process for making organohalosilanes

摘要

Silicon metalloid sample is heated above 2300 [deg]C with controlled ramp speed temperature to reduce the oxide impurities in the sample. The reduction is performed in presence of carbon source thereby effecting the formation of reduced products such as carbon dioxide and carbon monoxide. The specificity of silicon metalloid is determined by the amount of the reduced product obtained above 1900 [deg]C.
