Silver in modern life

Silver is far more than a precious metal. As the best conductor of electricity there is, it sits inside phones, solar panels and electric cars, and its shine makes mirrors work. It even helps keep water clean in space. Today, most silver is industrial.

This guide covers where silver turns up in modern life: electronics, solar panels, mirrors and jewellery, and why the metal is still so widely useful.

We tend to picture silver as coins and jewellery, but most of it now does quiet, practical work inside the technology around us.

Here are the questions people ask most about what silver actually does today. For the wider story, see the story of silver.

Why is silver used in electronics?

Silver carries electricity and heat better than any other metal, which makes it ideal for circuit boards, switches, connectors and touchscreens.

That is why electronics is now the single biggest industrial use of silver, from everyday phones to 5G and computing hardware.

Why is silver used in solar panels?

A fine silver paste forms the contact lines in solar cells, carrying away the electric current as sunlight hits the panel.

Because silver conducts so well, it remains the preferred choice for these contacts, and a large share of the world’s silver now goes into solar power.

UK-made colloidal silver, from £16.95

Most colloidal silver uses water purified once, if at all. We use two stages — reverse osmosis, then distillation — then bottle in dark glass. 10, 100 and 200 ppm, in dropper, spray or 500ml refill.

Why is silver used to make mirrors?

Silver reflects almost all the light that hits it, which is why it has long been used to coat mirrors and telescope optics.

The same bright reflectivity is used in everything from household mirrors to architectural glass and scientific instruments.

Does the Space Station use silver to keep its water clean?

Yes. The International Space Station uses silver in its life-support system to help keep recycled drinking water safe for the crew.

That is an engineered, specialist system, and a different thing from a consumer product like ours. We make no health claims, and our colloidal silver is sold for external use only.

Is silver used in electric cars?

Yes. Electric vehicles use silver throughout their electrical systems, where its conductivity makes for light, reliable connections.

  • Battery systems — moving power efficiently with minimal loss.
  • Power electronics — the controllers that manage that power.
  • Onboard connections — the many contacts a modern car relies on.

Our place in silver’s modern story is a modest one by comparison.

We make carefully produced colloidal silver here in the UK, bottled in dark glass — a small, everyday product made with the same respect people have shown this metal for centuries.

Why buy from Health is a Choice

We make our colloidal silver in the UK, the way we would want it for our own family. We don’t purify our water once — we do it twice.

It is first cleaned by reverse osmosis, then distilled on top of that, before we suspend real silver in it and bottle it in dark glass — never plastic.
