ABSTRACT:
There is described a method of closing ends of silicon tubular bodies in which the tube end to be closed is dipped into melt of silicon maintained at substantially the melting temperature of silicon until the end of the tube is heated to the melting point and then withdrawing the tube from the melt with melt temperature sufficiently low to cause freezing of molten silicon at tube end and at temperature and speed sufficient to cause decreasing diameter of the freezing silicon until the desired diameter reduction or closure is obtained and then breaking contact with the melt. Additionally, surface portions may be machined after withdrawal from the melt to allow connections to be made.
