Surface of silicon rod
Thread Content
In reduction furnaces, the high content of hydrogen chloride in the recovered hydrogen leads to a bark-like appearance on the surface of silicon rods. What are people’s opinions on this?
Cut off the hydrogen chloride and carry out cryogenic hydrogenation, then check the surface condition of the silicon rod
Silicon rod or silicon core? I encountered peeling when using silicon cores in the initial stage
The analytical tower in the dry-system isn’t working; if the issue with analysis can’t be resolved, it’s recommended not to recycle the gas used for regenerating the adsorption column, but instead send it elsewhere

Will there still be hydrogen available if it’s sent to another place?
Hydrogen chloride hyperhydrogen often causes corrosion; it is likely due to poor control of dichlorodihydrosilicon. Without the need to add any additional equipment, there are two solutions；
