Uses of Platinum (Pt) in Everyday Life
From the Platinum page's study notes: Platinum (Pt) serves in alloys, infrastructure and the technologies of daily life. The full list, with Bangladesh examples, sits below.
Looking for Platinum's uses without wading through a whole chapter? Here is the direct answer first, then the tables and derivations examiners want to see. Every number on this page comes from the same engine that powers the interactive table. Need the whole picture instead — history, characteristics, uses, exam questions?

Platinum at work around you
Every use below comes straight from the full Platinum 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 Platinum in the study notes
- Catalytic converters on modern vehicles: a honeycomb washcoated with platinum (with palladium and rhodium) converts poisonous carbon monoxide and nitrogen oxides into carbon dioxide and nitrogen gas.
- Platinum crucibles and dishes in analytical chemistry — rock powders can be fused in them with caustic flux and the vessel still weighed afterwards, because nothing reacts with it.
- Cisplatin-family chemotherapy drugs, whose central platinum atom crosslinks tumour DNA — the regime that made testicular cancer largely curable.
- Prestige wedding rings and watch cases — hypoallergenic and never tarnishing — plus fine electrodes, glassmaking stirrers and the retired international prototype kilogram of platinum–iridium.
Where you meet it
- A newish bus or car on Bangladeshi roads cleans its exhaust through a platinum-containing converter before the gas ever leaves the tailpipe.
- Jewellery counters in Dhaka malls stamp “PT 950” on platinum bands — 95% pure, chosen because it never blackens the skin the way some alloys do.
- Cancer wards worldwide stock cisplatin vials; the platinum atom at the drug’s heart is what jams the tumour cell’s DNA-copying machinery.

Why is Platinum important in Bangladesh?
The full study page connects Platinum 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 Platinum in the NCTB exam?
Questions on Platinum'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.
