RHENIUM SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Renyum
Rejen sembolü Re ve atom numarası 75 olan bir kimyasal elementtir. Bu, periyodik tablonun 7. grubundaki gümüşi beyaz, ağır, üçüncü sıra geçiş metalidir. Reeliyum, milyar başına 1 parçanın tahmini ortalama konsantrasyonu ile Dünya'nın kabuğundaki nadir elementlerden biridir. Serbest elemanın üçüncü en yüksek erime noktası ve herhangi bir elementin en yüksek kaynama noktası vardır. Renyum, manganez ve teknetiyum ile kimyasal olarak benzer ve molibden ve bakır cevheri ekstraksiyonunun ve arıtmasının yan ürünü olarak elde edilmektedir. Renyum, bileşiklerinde -1 ile +7 arasında değişen çok çeşitli oksidasyon durumlarını gösterir. 1925 yılında keşfedilen renyum, keşfedilecek en istikrarlı elementtir. Avrupa'daki Ren Nehri'nin adını aldı. Renyumun nikel esaslı süper alaşımları, yanma odaları, türbin kanatları ve jet motorlarının egzoz püskürtme uçlarında kullanılır. Bu alaşımlar% 6'a kadar renyum içerir, jet motoru yapımı element için en büyük tek kullanımlık haldedir; kimya endüstrisinin katalitik kullanımları en çok önemlidir.
İngilizce sözlükte rhenium sözcüğünün tanımı
Sözlükte renyumun tanımı, yüksek bir erime noktasına sahip yoğun bir gümüşi-beyaz metalik elementtir. Genellikle gadolinit ve molibdenitte bulunur ve yüksek sıcaklık termokupllarında tungsten veya molibden ile alaşımlanmış olarak kullanılır. Sembol: Re; atom numarası: 75; atom ağırlığı: 186.207; değerlik: -1 veya 1-7; göreceli yoğunluk: 21.02; Erime noktası: 3186 ° C; Kaynama noktası: 5596 ° C.

Occurrence and Uses Rhenium (Re) is found in the combined state in platinum
ores, gadolinite, molybdenite (MoS2) and columbite. It is found in some sulphide
ores. It is a rare element making up about 0.001 ppm of the Karth's crust.
