Uses of Cadmium (Cd) in Everyday Life
From the Cadmium page's study notes: Cadmium (Cd) serves in alloys, infrastructure and the technologies of daily life. The full list, with Bangladesh examples, sits below.
Looking for Cadmium'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?

Cadmium at work around you
Every use below comes straight from the full Cadmium 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 Cadmium in the study notes
- Nickel-cadmium (Ni-Cd) rechargeable batteries — the rugged cells that long powered emergency lights, cordless phones and power tools in Bangladeshi homes.
- Cadmium sulfide and selenide pigments — the brilliant cadmium yellow and cadmium red of artists’ oil paints and older bright plastics.
- Electroplated cadmium coatings that sacrifice themselves to shield steel bolts and aircraft parts from rusting in salty air.
- Neutron-hungry control rods for nuclear reactors; cadmium selenide quantum dots still light up premium QLED television screens.
Where you meet it
- The elderly Ni-Cd battery pack inside a household emergency lamp or an old cordless phone.
- Cigarette smoke carries cadmium deep into the lungs — smokers typically carry roughly twice the cadmium burden of non-smokers.
- Rice grown on cadmium-contaminated soil can pass the metal into its grains — one reason food regulators watch heavy-metal levels so strictly.

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