摘要： Vaporized silicon halide is mixed with a vaporized alkali metala in a reactor chamber in an exothermic reaction producing liquid silicon droplets and gaseous alkali metal halide, and then passed out of the reactor chamber through a nozzle in a supersonic jet. The supersonic jet is produced by utilizing vacuum means to maintain the exit chamber at a lower pressure than the reactor chamber. Separation of the silicon from the salt by-products is performed by shock wave impaction separation technique wherein the products of the complete reaction between the alkali metal and silicon halide are made to impinge upon an unrestricted, flat surface so that the direction of flow of the gas changes abruptly and a shock zone is created above the flat surface. The silicon droplets are carried by their large forward momentum through the shock zone onto the separating surface where they are deposited. The gaseous alkali metal halide flows across the surface and is thus separated from the silicon product. The silicon droplets are removed in a variety of physical configurations to produce silicon in pellet form, sheet form, ingot form, or single crystal silicon.
摘要翻译：将蒸发的卤化硅与反应室中的汽化碱金属在放热反应中混合，产生液体硅液滴和气态碱金属卤化物，然后通过超声波喷嘴的喷嘴从反应室中排出。通过利用真空装置将出口室保持在比反应器室低的压力下来产生超音速喷射。通过冲击波冲击分离技术进行硅与盐副产物的分离，其中将碱金属和卤化硅之间的完全反应的产物撞击在无限制的平坦表面上，使得流动方向气体突然变化，并且在平坦表面上方产生冲击区域。硅液滴通过其较大的向前动量通过冲击区承载在其沉积的分离表面上。气态碱金属卤化物流过表面，因此与硅产物分离。以各种物理构型去除硅液滴，以产生粒状，片状，锭状或单晶硅的硅。

摘要： A grinding wheel is used to pulverize solid test samples and propel particles thereof into a flame for analysis by an instrument such as a mass spectrometer. The sample is attached to one end of a pivoted lever arm. The other end of the lever arm is connected to a solenoid. Activation of the solenoid brings the sample into contact with the rotating grinding wheel. The solid particles produced by the wheel are propelled into the flame through a slot in an intermediate draft shield. The sampling cone of a conventional mass spectrometer or similar instrument may be placed in the flame to analyze the nature of the test materials. The device may also be used to inject test particles into the air or gas feed stream ahead of the flame if desired.
