| titleOfInvention | A method for manufacturing polycrystalline silicon frits and a method for controlling the surface metal concentration of polycrystalline silicon frits |
| abstract | The present invention includes a step of manufacturing a polycrystalline silicon rod by the Siemens method, a step of crushing the polycrystalline silicon rod to obtain a polysilicon crushed product, and a step of etching and cleaning the polycrystalline silicon crushed product in a cleaning tank, wherein the cleaning In the step, a group of polycrystalline silicon fragments having a controlled shape and size is placed in a cleaning tank, and a change in weight of the polycrystalline silicon fragment group before and after etching is measured to control the cleaning process; It relates to a method for manufacturing a polycrystalline silicon frit. The present invention also relates to a method for controlling the surface metal concentration of polycrystalline silicon frit. |
