Abstract
Description
(A)ガラス溶融物を耐火容器中で取り扱う工程であって、浮遊粒子を含む雰囲気にガラス溶融物を暴露させる工程;および
(B)その雰囲気中に電場を形成し、その電場を発生させている少なくとも1つの電極の表面で粒子を収集することによって粒子を低減させる工程であって、電場がガラス溶融物に電位勾配を実質的に与えないものである工程
を含むガラスの製造方法が提供される。
したがって、周りの雰囲気中の酸素の存在下、Pt容器の高温表面はPtO2ガスへと酸化される。これはより低い温度の他の表面または媒体(雰囲気など)と接触すると、分解して固体のPtを生成し得る。固体Ptは徐々に十分に大きな粒子に成長し、その後、ガラス溶融物中に落下し、最終ガラス成形品に包有物を形成する。
Claims (7)
