GLASS TUBE AND GLASS CAP FOR FABRICATION OF CRYSTALLINE AND AMORPHOUS MATERIALS AND THEIR SEALING METHODS

摘要

PURPOSE: A glass tube and a glass cap for manufacturing crystalline and amorphous materials and a sealing method of the same are provided to improve the quality of crystalline and amorphous materials by reducing contamination. CONSTITUTION: A glass tube(10) and a glass cap are prepared. A groove part(12) or a stepped part is formed at one part of the glass tube. The glass cap is inserted into the end part of the glass tube. Heat is applied to the middle of the glass tube to form one or more groove parts into the glass tube. The stepped part is formed by adjacently arranging two glass tubes and applying heat to the attached parts of the glass tubes.
