Abstract

　鉛成分を含有せず、希土類酸化物とフッ素を同時に含有するガラス系において、鉛ガラスに匹敵する遮蔽能力を有し、しかも表面硬度が高く可視域での透明性が極めて高いガラス組成物を提供すること。 　酸化物基準の質量％で、Ｌｎ２Ｏ３（ＬｎはＬａ、Ｙ、Ｇｄ、Ｔｂ、Ｄｙ、Ｙｂ、Ｌｕからなる群より選択される１種以上を示す。）を１～８５％、フッ素を０．１～２０％含有し、１５０ｋＶのＸ線に対する鉛当量が０．０３ｍｍＰｂ／ｍｍ以上であるガラス組成物である。また、ＳｉＯ２及び／又はＢ２Ｏ３及び／又はＧｅＯ２及び／又はＰ２Ｏ５の合計量を１０～７０％含有させることで、失透に対して安定で、表面硬度が高く透明性も放射線遮蔽能力も優れたガラス組成物を得ることができる。
