Description
最小T35k-Tliq=0.25T35k-225、 (1)
にしたがって表すことができる。式中、全ての温度は℃で表されている。それゆえ、例示のガラスの1つ以上の実施の形態は、T35k-Tliq>0.25T35k-225℃を有する。
SO4 =→SO2+O2+2e-
などの半反応に関して記載でき、式中、e-は電子を示す。この半反応の「平衡定数」は
Keq=[SO2][O2][e-]2/[SO4 =]
であり、式中、角括弧は化学的活性を示す。理想的には、その反応により、SO2、O2、およびe-から硫酸基を作らせたい。硝酸塩、過酸化物、または他の酸素の豊富な原材料を添加することは、役立つてあろうが、溶融の初期段階における硫酸基の還元に不利に働くかもしれず、これは、初めの段階で、それらを添加する利益を無効にするであろう。SO2は、ほとんどのガラス中に非常に低い溶解度を有し、よって、ガラス溶融過程に加えることが実際的ではない。電子は、還元された多価元素により「加えられる」であろう。例えば、第一鉄(Fe2+)の適切な電子供与半反応は
2Fe2+→2Fe3++2e-
と表される。
