METHOD FOR PRODUCING GLASS ARTICLE |
摘要 |
<p>A glass article is produced at a high production rate and a high yield by jetting a glass-forming raw material from a multi-port burner, synthesizing glass soot through hydrolysis of the glass-forming raw material, depositing the glass soot to form a soot preform and heating and vitrifying the soot preform to produce a transparent glass article, wherein the glass-forming raw material is vaporized by heating it at a temperature higher than its boiling point and directly supplied to the burner, the vaporized glass-forming raw material and a fuel gas for synthesizing glass soot are supplied to an inner port of the multi-port burner and a fuel gas for heating a formed preform is supplied to an outer port of the multi-port burner, and a molar ratio of water generated by a reaction of the fuel gas for synthesizing glass soot to the glass-forming raw material is from 2 to 3. <IMAGE></p> |
