<P>PROBLEM TO BE SOLVED: To provide a method for producing silicate glass having excellent foam quality by using tin oxide. <P>SOLUTION: When silicate glass is produced, tin oxide powder whose median particle size D<SB POS="POST">50</SB>is in the range of 2-50 μm is used as a refining agent. As the silicate glass, alkali-free glass or lithium aluminosilicate-based crystallized glass can be named for example. <P>COPYRIGHT: (C)2013,JPO&INPIT |
