Description
クリープおよび/またはその変化を低減するために、他の材料がこれまでにも提案された。しかしながら、大きいアイソパイプにとって、クリープ率は依然として高すぎるものである。
【発明の概要】
【発明が解決しようとする課題】
本発明は、焼結の間の材料の高密度化を最大化し、使用の間のクリープ率を最小化するための、ジルコンにおける焼結助剤の使用方法について記載する。
【課題を解決するための手段】
から実質的に構成される複合材料が提供され、ここで、焼結助剤の量は、組成物の総重量の酸化物に基づいた重量%である。
(i)少なくとも1μmの平均粒径を有するジルコン粉末、ある実施の形態では少なくとも3μm、ある実施の形態では少なくとも5μm、ある実施の形態では少なくとも7μm、ある実施の形態では少なくとも8μmである、ジルコン粉末を提供する工程と、
(ii)焼結助剤または、以下に示す量のタイプI,タイプIIおよびタイプIII、およびそれらの組合せから選択される焼結助剤前駆体:
を提供する工程と、
(iii)前記ジルコン粉末と焼結助剤またはそれらの前駆体とを混合して、焼結助剤が実質的に均一に分布した混合物を得る工程と、
(iv)前記混合物を加圧して予備成形物を得る工程と、
(v)前記予備成形物を高温で焼結して焼結物品を得る工程と、
を有してなる方法が提供される。
本発明のある実施の形態のいくつかの利点としては、とりわけ、(i)ジルコン中の焼結助剤の使用量が少なく、焼結助剤合計で1%未満であること;(ii)粒界をピンニングするための高温耐火性の酸化物の使用が、最終的に材料を室温および高温の両方において強化し、粒界を高温および低い応力下で不動にすること;(iii)ジルコン組成物における焼結助剤のマイナスの影響が最小限に抑えられること;および(iv)ナノ助剤が、低濃度において最大の影響力を提供することが挙げられる。
【実施例】
