Long whiskers on the silicon rod crossbeam
Thread Content
Yesterday, whiskers appeared on the crossbeam of the silicon rod, causing a grounding fault. What caused this and how can it be prevented? ? ? ?

Please provide a diagram; I don’t know what kind of ‘xu zi’ you’re referring to – without a diagram, there’s no way to know for sure.
If it is what you mentioned, causing grounding, then it should be due to the melting of silicon at the beam area; what’s needed is to control the temperature properly, and also to ensure that the silicon cores are joined as tightly as possible!
No picture? That’s too abstract; if the crossbeam melts too much and drips onto the graphite seat, it could cause a short circuit between the graphite seat and the chassis, which in turn would trigger a ground fault alarm. .
It’s not a problem with the melting of silicon in the crossbeam; it’s because the ends of the crossbeam are long and aligned with the direction of the air flow. As they get longer, they naturally touch the walls of the furnace, which then triggers a ground fault alarm. That component is extremely thin, and when it reaches a certain temperature, self-heating occurs and silicon deposits form
What on earth is a \"xu zi\"? I’ve never seen it before; the term \"mustache\" seems to have some other meaning as well. I really want to see pictures; the original poster must be getting old. .
