Silicon core wire
In the silicon core wire according to a first aspect of the present invention, a male thread part formed at one end of a first thin silicon rod and a female thread part formed at one end of a second thin silicon rod may be screwed together and fastened. In the silicon core wire according to a second aspect of the present invention, a thread part formed at one end of a first thin silicon rod and a thread part formed at one end of a second thin silicon rod may be screwed together and fastened via an adapter with thread parts formed at both ends.
1. A silicon core wire,
wherein a male thread part formed at one end of a first silicon rod and a male thread part formed at one end of a second silicon rod are screwed together and fastened via an adapter with female thread parts formed at both ends,
wherein the adapter covers the male thread part formed at the one end of the first silicon rod and the male thread part formed at the one end of the second silicon rod from outside, and wherein the adapter is a silicon member.
2. The silicon core wire according to claim 1 , wherein the first silicon rod and the second silicon rod are silicon rods collected from a polycrystalline silicon rod or a monocrystalline silicon rod.
