Abstract
Description
室温にて液体形態で存在する少なくとも1つの重合性有機バインダーと、
それぞれ光又は熱の供給によって少なくとも1つの重合性有機バインダーの重合又は架橋を開始する重合開始剤又は架橋剤と、
少なくとも1つの重合性有機バインダー中に分散形態で存在し、7nm〜100nmの範囲の直径を有する少なくとも1種類の球状石英ガラス粒子と、
を含む。
(a)高純度透明石英ガラス製の成形品を製造するための上記で特徴付けた本発明の組成物をデバイス内に供給する工程と、
(b)組成物中に含まれる少なくとも1つの重合性有機バインダーを光又は熱の供給によって硬化させ、それにより一次構造としてグリーン体を得る工程と、
(c)硬化していない可能性がある少なくとも1つの重合性有機バインダーを、それに含まれる成分を含めて一次構造から分離すると共に、工程(a)、工程(b)及び任意に工程(c)を任意に少なくとも1回繰り返す工程と、
(d)任意に、フォーミングツールを用いた構造化、高エネルギー放射線の照射及びその後の現像、フライス加工、ドリル加工、ラミネート加工、接着、研削、研磨、ラッピング、彫刻、及び熱又はレーザー光による処理からなる群から選択される少なくとも1つの工程によって一次構造を後処理する工程と、
(e)一次構造中に存在する可能性がある非硬化性成分を除去する工程と、
(f)一次構造を熱処理により脱バインダーし、それにより多孔質二次構造としてブラウン体を得る工程と、
(g)任意に、多孔質二次構造に少なくとも1つのフィラーを充填する工程と、
(h)多孔質二次構造を焼結し、それにより最終成形品を得る工程と、
を好ましくはこの順序で含む、方法を提供する。
層厚1mmにて波長200nmで少なくとも70%、すなわち70%以上の光透過率、更には200nm〜1000nmの波長範囲で70%より大きい、すなわち70%超の光透過率、
DIN EN ISO 6507に従って測定された、799HVのビッカース硬さ、及び、
DIN EN ISO 6872に従って測定された、100MPaの二軸曲げ強度。
以下の成分を含む組成物を、50mL容ガラスビーカー内に準備した:
重合性有機バインダーとしての8.25mLのヒドロキシエチルメタクリレート及び3mLのテトラエチレングリコールジメタクリレート、
非硬化性成分としての3.75mLのフェノキシエタノール、
光活性化可能なフリーラジカル開始剤としての0.6gの2,2−ジメトキシ−2−フェニルアセトフェノン、
吸収剤としての6mgのSudan Orange G、並びに、
10nm〜100nmの範囲の直径を有する25gの石英ガラス粒子(ここでの平均直径は40nmであった)。
加熱速度:0.5K/分、25℃→150℃、保持時間:4時間
加熱速度:0.5K/分、150℃→280℃、保持時間:4時間
加熱速度:1K/分、280℃→550℃、保持時間:2時間
冷却速度:5K/分、550℃→25℃、終了
加熱速度:5K/分、25℃→800℃、保持時間:2時間
加熱速度:3K/分、800℃→1300℃、保持時間:1.5時間
冷却速度:5K/分、1300℃→25℃、終了
ブラウン体を実施例1と同じ条件下で得た。塩化金(III)によるブラウン体中に存在するキャビティの充填は、コロイダルレッド(colloidal red)の着色を生じ、硝酸クロム(III)による充填はイオニックグリーン(ionic green)の着色をもたらした。この目的で、ブラウン体を0.1質量%のAuCl3及びそれに対応して0.5質量%のCr(NO3)3を含むエタノール溶液に含浸した後、50℃で1時間乾燥させた。焼結は、約0.1ミリバールの圧力の窒素下で実施例1の温度プロファイルを用いて達成した。焼結後に得られた石英ガラス成形品は、いずれの場合も着色されていた。これは透過スペクトルでも明らかである(図5)。

重合性有機バインダーとしての12.8mLのヒドロキシエチルメタクリレート、
非硬化性成分としての4.3mLのフェノキシエタノール、
