METHOD FOR PRODUCING GLASS SPHERE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a glass sphere used for forming an optical lens and the like with high productivity. <P>SOLUTION: When the glass sphere is produced by dropping molten glass 2, bubbles in the molten glass can be removed because of its low viscosity in a crucible to remove striae by controlling a melting temperature controlling means 8 and a droplet temperature controlling means 9 particularly so that the temperature of the molten glass 2 in the crucible 1 is higher than the temperature of a glass droplet 7 pouring from a nozzle 3. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
