Abstract
Description
"International Journal of Impact Engineering",27.5.2002,509−520には、例えば、HEL(Hugenostic Elastic Limit:ユゴニオ弾性限界)が弾動防護としてのセラミックの作用に対して決定的な大きさであることが報告されている。さらに、HELに対する多孔性の強い影響が確認される。より大きな細孔−数および寸法比において−は、前記HEL、ひいては防護効果を減少させる。
− 2mmの厚さの研磨された板に対して600nmの波長の光で測定された、75%超のRITを有する、10μm超ないし100μm以下の範囲内の平均粒径を有する透明セラミック、特に10μm超ないし50μmの範囲内の平均粒径を有する透明セラミック、特に有利に10μm超ないし20μmの範囲内の平均粒径を有する透明セラミック、殊に有利に11〜20μmの範囲内の平均粒径を有する透明セラミック。
好ましくは、上記の記載と同様の透明セラミックであり、これは、
− 高い光学的品質を有し、
− 10%未満の斑点頻度、特に有利に1%未満の斑点頻度を有し、
− 第二相の寸法が最大2000μm未満、特に200μm未満である第二相を有し、
− ジルコニウム、アルミニウム、マグネシウム、イットリウム、亜鉛、錫、カルシウム、チタン、ガリウム、インジウム、ハフニウム、スカンジウム、セリウム、ユーロピウム、バリウムまたはこれらの組合せからなる酸化物の1つを含有し、
− Mg−Alスピネル、AlON、酸化アルミニウム、イットリウムアルミニウムガーネット、酸化イットリウム、酸化ジルコニウムを含有し、
− AlONを含有し、
− スピネルセラミックである。
スピネル粉末(MgAl2O4)を50質量%のスリップに加工する。この希薄粘稠なスリップを引き続き偏心スクリューポンプを用いて流動層造粒装置内に噴霧する。粉末床として先に純粋な粉末を前記装置内に供給する。遅速の連続的なスリップ供給によって、前記材料を次第に連続的に造粒する。圧力比ならびに供給空気量を、顆粒がd10=100μmおよびd90=300μmの寸法範囲内で製造される程度に調節する。こうして製造された顆粒は、いかなる不均一性、例えば中空球構造またはドーナツ形状も有しない中実顆粒である。前記顆粒を引き続き160MPaで一軸的に圧縮成形して50mm×50mmの寸法を有する板にする。この板は、当該板の均一性のために1500℃で緻密に焼結されうる。その後に、HIPプロセスを同様に1500℃および2000バールで行なう。HIPプロセス後に、3.575g/cm3の測定された密度がもたらされ、この密度は、DIN EN 623−2と同様にアルキメデス法により測定される。これは、99.9%超の密度を表わす。この高い均一な密度から、製造された前記板内で0.2%の変動率をもって83%のRIT値がもたらされる。存在する斑点の割合は、0.5%以下である。DIN EN 623による直線交差法により算出された、前記セラミックの平均粒径は、研磨された当該試験体の熱的エッチング後に12μm±0.5μmである。
透明セラミックを製造する場合には、たいていの試験体の際に澄明な試験体が生じるのではなく、全ての試験体には数μmないし数100μmの寸法範囲内の斑点が混じっていることが判明する。この理由から、前記試験体を分析しかつ定量化する必要性がもたらされる。それというのも、前記斑点は、本発明によるセラミックから完成された、後の構造部材の外観を目視的に見て妨げになるからである。さらに、様々な試験体には異なる強さで前記斑点が混じっていることが判明する。当該例は、図1に表わされている。図1は、純粋な粉末からなる、冷間等方圧加工法で圧縮成形された試験体の写真を示す。
