A cyclic adiabatic compression reactor is used for the Si powder fabrication by the monosilane decomposition in a gas mixture with argon. Along with arbitrary agglomerations of Si nanoparticles, this method allows synthesizing nanoparticle chains and nanowhiskers, as an outlet gas pressure in the reactor increases from about 2.0 to 5.0 MPa. The increase in pressure corresponds to an increase in temperature from ~450 to 1050 °C, which leads to a change in the particle structure from amorphous to crystalline and reduces the particle size distribution. The particle chain and nanowhisker formation is associated with an increase in the duration of the synthesis process. The optical properties of the synthesized Si powders were determined by Si/SiO₂ interfaces appeared by the oxidation in the air. The method is characterized by a relatively high production rate of Si powders of various morphologies, which may be of interest for various applications.

循环绝热压缩反应器用于通过在与氩气的气体混合物中的甲硅烷分解来制造 Si 粉末。随着 Si 纳米粒子的任意团聚，该方法允许合成纳米粒子链和纳米晶须，因为反应器中的出口气压从约 2.0 增加到 5.0 MPa。压力的增加对应于温度从 ~450°C 增加到 1050°C，这导致粒子结构从无定形变为结晶并减小粒度分布。粒子链和纳米晶须的形成与合成过程持续时间的增加有关。合成硅粉的光学性能由Si/SiO _{2 决定}由于空气中的氧化而出现界面。该方法的特点是各种形态的硅粉的生产率相对较高，这可能对各种应用感兴趣。
