希少 Re レニウム 99.99% 50g ペレット レアメタル 成分分析表付

地球上で極めて希少なレニウムを内部まで完全に溶融・凝固させて成形した重量級ペレットで、金属光沢と驚異的な重量感をお楽しみいただける、コレクター・研究者向けの最高級標本です。 【レニウムとは】 レニウム(Re)は、全元素中でも最も希少な安定元素の一つで、地球地殻中の存在量は金よりも少なく、年間生産量も数十トン程度です。超高温耐性(融点3186℃)と耐食性に優れ、超音速ジェットエンジンのタービンブレード、火箭ノズル、腐食耐性合金として航空宇宙・軍事分野で極めて重要な戦略金属です。純度99.99%という高純度レニウムは、研究・評価用素材として世界的に入手困難です。 【溶融ペレットならではの特徴】 粉末焼結品とは異なり、内部まで完全に溶融・凝固させた本品は、極めて高いち密性と均質性を誇り、50gという大型サイズながら滑らかな表面仕上げを実現しています。再溶解、単結晶成長、特殊合金母材、高温材料試験など、先端研究での即戦力素材として最適です。そのずっしりとした重量感(密度21.0g/cm)は、手にした瞬間にレニウムの希少性と価値を実感いただけます。 【コレクション・研究用途としての価値】 このレニウム溶融ペレットは、「レニウム大型標本」として、元素コレクター・希少金属愛好家・材料科学者にとって一生モノの逸品です。99.99%の高純度により、単なる標本を超え、実際に航空宇宙材料研究や高額トレーディング素材としても活用可能。まさに「持つだけで資産価値が上がる」一品です。
