Uses of Ruthenium (Ru) in Everyday Life
From the Ruthenium page's study notes: Ruthenium (Ru) serves in alloys, infrastructure and the technologies of daily life. The full list, with Bangladesh examples, sits below.
Teachers call it "one fact, fully handled" — exactly what this page does for Ruthenium. The answer sits at the top in bold; scroll for the working, the shell-by-shell breakdown and the two questions students ask most. Need the whole picture instead — history, characteristics, uses, exam questions? The full Ruthenium page is one click away.
Ruthenium at work around you
Every use below comes straight from the full Ruthenium study page, where each point also carries the chemistry behind it and an exam-style question. Skim the list here; open the full page when revision time comes.
Uses of Ruthenium in the study notes
- Ultrathin ruthenium layers inside hard disk drives keep magnetic bits stacked upright — every laptop and external HDD relies on them.
- -coated electrodes for factory chlorine production from brine — the chlorine behind water treatment and bleach.
- Grubbs-type catalysts for building fine chemicals, pharmaceuticals and advanced plastics.
- Platinum-ruthenium alloys for long-life electrical contacts, fountain-pen nib tips and aircraft spark plugs.
Where you meet it
- The hard drive inside a school or office computer — its dense storage would be impossible without ruthenium interlayers.
- The chlorine that treats drinking water and keeps swimming pools clean is often made using ruthenium-coated electrodes.
- A quality fountain pen’s iridium-tipped nib usually contains ruthenium in the alloy ball at its point.

Why is Ruthenium important in Bangladesh?
The full study page connects Ruthenium to Bangladeshi life — school labs, local industries, health and the NCTB syllabus. This quick-answer page is the fast summary; the element page is the full story.
Where will I meet Ruthenium in the NCTB exam?
Questions on Ruthenium's uses are a recurring pattern in Class 9–10 and HSC chemistry. The element page ends with six exam-style questions in both languages — practise those and this pattern stops costing marks.
