REFRACTORY OBJECT FOR USE IN FORMING GLASS OBJECT
PROBLEM TO BE SOLVED: To provide a refractory object including a glass overflow trough and a glass overflow forming block which has a long lifetime and can prevent contamination by an undesired element that disadvantageously affects properties of produced glass.SOLUTION: A refractory object for use in forming a glass object has a composition of at least 95 wt.% of AlOand 0.05-5 wt.% of a dopant containing TaO, MgO, ZrO, HfO, YO, YbO, PrO, LaO, GdO, CeO, DyO, or any combination of these.
【課題】寿命が長く、かつ製造されるガラスの特性に悪影響を及ぼす望ましくない元素による汚染を防ぐことができる、ガラスオーバーフロートラフおよびガラスオーバーフロー成形ブロックを含む耐火物の提供。【解決手段】ガラス体の成形に用いられる耐火物を、少なくとも９５ｗｔ％のＡｌ２Ｏ３と、０．０５〜５ｗｔ％のＴａ２Ｏ５、ＭｇＯ、ＺｒＯ２、ＨｆＯ２、Ｙ２Ｏ３、Ｙｂ２Ｏ３、Ｐｒ２Ｏ３、Ｌａ２Ｏ３、Ｇｄ２Ｏ３、ＣｅＯ２、Ｄｙ２Ｏ３またはこれらの任意の組み合わせを含むドーパントとからなる組成とする。【選択図】図２
