以下に提示する実施例は、上述した組成を有する焼結セラミック構成要素が、1600℃未満の焼結温度で形成され、所望の密度及び外観を達成し得ることを示す。焼結セラミック構成要素は、選択されるドーパントとドーパント濃度に応じて、異なる色を有し得る。サンプルを生成して、焼結温度、1550℃で4時間焼結した場合の密度、及び焼結材料の色情報を分析した。
異なる組成を有するサンプルを生成した。1つのサンプルは、不純物が比較的多い商業用等級の従来の出発材料を使用して作製し、不純サンプルと称した。比較的低い不純物レベルを有する出発材料でサンプルを作製し、純粋1サンプル及び純粋2サンプルと称した。下記の表1及び表2は、不純サンプル、純粋1サンプル及び純粋2サンプルの粒子サイズ分布及び組成を含む。粒子サイズ分布に関して、d10、d50、及びd90は、不純及び純粋サンプルの10パーセンタイル値、50パーセンタイル値、及び90パーセンタイル値を表す。
サンプルに関する膨張曲線を生成した。膨張曲線は図1〜8に含まれ、これらの図は、1600℃に加熱中の温度の関数としての%dL/dTを有する。図1は、不純サンプルの膨張曲線を含む。図2及び3は、純粋1及び純粋2サンプルの膨張曲線を含む。図4〜8は、選択されたドープ及び共ドープサンプルに関する膨張曲線を含む。
不純サンプルは、良好な焼結及び緻密化特性を有する;しかしながら、不純サンプルは、使用されている商業用等級の出発材料に起因して、高いレベルの不純物を有する。純粋1サンプルは白色の外観を有するが、1550℃で4時間暴露された際の密度は83%である。ある用途においては、少なくとも95%の緻密化が必要であり又は所望され得る。従って、焼結が1600℃を超える温度で行われ、又は1600℃以下での暴露が長時間である必要があり、これらは両方とも望ましくない。純粋1及び純粋2サンプルは、非常に低いレベルの不純物を有し、白色の外観を有する。純粋1サンプルと比較すると、純粋2サンプルは有意に高いZrO2含有率を有する;しかしながら、そのようなZrO2含有率にあっても、純粋2サンプルは尚、十分良好な焼結及び密度特性を有さない。
