Abstract

U ovom radu je detaljno opisan povijesni razvoj rutenija, rodija, paladija, srebra, osmija, iridija, platine i zlata. Opisana su njihova karakteristična svojstva, ekonomska vrijednost i područja primjene. Tih osam metala je, zbog svojih karakterističnih svojstava, svrstano u posebnu skupinu pod nazivom plemeniti metali. Uvodno se navode neke općenite karakteristike koje vrijede za sve elemente ove skupine, a dalje se svaki element zasebno razmatra. Opisana je povijest svakog elementa i njegovo otkriće, te jedinstvena svojstva poput otpornosti na koroziju, toplinske i električne vodljivosti i slično. Ta svojstva dopuštaju plemenitim metalima da se koriste za različite primjene u brojnim i raznolikim industrijama (tekstilna, elektronska, industrija nakita...). U radu je posebno naznačeno u kojoj mjeri su plemeniti metali postali dio svakodnevnog ljudskog života i koliko raširenu, te bitnu svrhu imaju od primjene u katalitičkim pretvornicima za smanjenje onečišćenja okoliša do upotrebe kod lijekova za liječenja tumora. Zaključno je dan osvrt na važnost plemenitih metala i ogromnu ulogu koju su imali na ljudsku civilizaciju i njezin razvoj.

Abstract (english)

This paper describes in detail the historical development of ruthenium, rhodium, palladium, silver, osmium, iridium, platinum and gold. Their characteristic properties, economic value and areas of application are also described. Due to their characteristic properties, these eight metals are classified in a special group called precious metals. In the beginning, some general characteristics that apply to all elements of this group are stated, and then each element is observed separately. The history of the creation of each element and its discovery are described as well as its unique properties, such as resistance to corrosion, thermal and electrical conductivity, and the like. These properties allow noble metals to be used for a variety of applications in many and varied industries (textile, electronic, jewelry industry...). The paper specifically indicates the extent to which precious metals have become a part of everyday human life and how widespread and important their purpose is, from being used in catalytic converters to reduce environmental pollution to being used in drugs for the treatment of tumors. In the end, a review is given of the importance of noble metals and the huge role they played in human civilization and its development.
