以下に示す方法で、生体溶解性、誘電正接、作業温度範囲、耐水性及び分相の評価を実施した。実施例1~6の結果を表1に、比較例1~5及び参考例の結果を表2に、それぞれ示す。
まず、溶融固化後のガラス組成が、表1に示された実施例1~6及び、表2に示された比較例1~5及び参考例の各組成となるように、ガラス原料を混合し、ガラスバッチを得た。次に、得られたガラスバッチを白金ルツボに入れ、この白金ルツボを、1500~1600℃の範囲の温度の、各実施例、各比較例及び参考例のガラスバッチの溶融に適した温度条件で、電気炉中に4時間保持し、ガラスバッチに撹拌を加えながら溶融させることにより、均質な溶融ガラスを得た。次に、得られた溶融ガラスをカーボン板上に流し出し、冷却して塊状のガラスカレットを得た。
まず、溶融固化後のガラス組成が、表1に示された実施例1~6及び、表2に示された比較例1~5及び参考例の各組成となるように、ガラス原料を混合し、ガラスバッチを得た。次に、得られたガラスバッチを80mm径の白金ルツボに入れ、1500℃~1600℃の範囲の温度で7時間溶融したものを、ルツボから取り出し、ガラスバルクを得た。次いで、得られたガラスバルクを、580~700℃の範囲の温度で、8時間焼き鈍し、試験片を得た。
回転粘度計付高温電気炉(芝浦システム株式会社製)を用い、白金ルツボ中で前述のガラスカレットを溶融し、回転式ブルックフィールド型粘度計を用いて溶融温度を変化させながら連続的に溶融ガラスの粘度を測定し、回転粘度が1000ポイズのときに対応する温度を測定することにより1000ポイズ温度を求めた。
生体溶解性の評価の際と全く同一の方法で、フィラメント径が13.0μmのガラス繊維サンプルを1.0g作製した。次に、80℃の温度の水中に前記ガラス繊維サンプルを24時間浸漬させた際の前後における、該ガラス繊維サンプルの質量減少率を測定した。
前記誘電正接測定用のガラスバルクの外観を観察した際に、透明又は若干白濁はあるがほぼ透明である場合に、分相を「A」、白濁が見られるが光は通す、又は、白濁している場合に、分相を「B」と評価した。
