Crystals what technological purpose can they be used for?
Okay the subject might be a bit vague.
But we see it in ALOT of sci-fi and sci.fi fantasy.

In Star Wars they are used as the focus lens for the light saber itself (i think)

In Stargate SG-1 they are mainly used as hard drives.

And in the old Superman (the Richard Donner version) The are more or less used for almost anything the writer can come up with.

My question is, at our current technological level and understand, do crystals have any use in our technology and if so what is it that makes them so useful and if not what is it about them that makes them more or less useless as anything but a pretty thing.

I think i heard somewhere that artificial diamonds (which would fall under the crystal idea) are great conductors and are good at transferring heat and such.
But other then that i have no idea what crystals can actually be used for in technology?

My question is, at our current technological level and understand, do crystals have any use what so ever or is it only in science fiction that they are useful for anything other then looking nice?

Sapphires are used as bearings, especially in watch movements.

Silica crystals are why sandpaper is called sandpaper.

Aluminum oxide crystals are what make modern sandpaper abrasive.

Carborundum crystals are what make other abrasives abrasive.

Diamonds are used in cutting.

Rubies are used for lasers.

And on and on.

Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method.

Well, we are also getting good at using crystals for data storage!

We use "crystals" for energy production too. Like Uraninite as an ore for Uranium in nuclear energy production.

Your watch probably says "quartz" on it because quartz is used to help the watch keep time by regulating an electronic oscillator.

Also, keep in mind that metals are crystalline too. Any mineral is a crystal or composed of aggregates of crystals. So you use crystals every day and even sprinkle solid cubes of Halite on your french fries to enhance the taste. We dissolve Fluorite to fluoridate our water. Crystals even rain from the sky in winter in a lot of places.

RE: Crystals what technological purpose can they be used for?
I could go on for days about how we use crystals or as how naturally occurring minerals form the basis for a lot of the products you use.

Kaopectate? Has Kaolinite in it.

Tums? Calcium Carbonate.

Glitter? Mica flakes (at least it used to be. Now it is mostly plastics).

Copper wire? Copper (and any other naturally occurring metals) are minerals themselves and are crystalline by definition.

Like hershey chocolate bars? Know why they break off so nicely into pieces? It's because they have some clay in them and clay is a group of minerals.

Talcum powder/baby powder? The mineral talc.

Write with a lead pencil? You're using graphite.

Azurite is a common mineral used for blue dyes and coloring.

Barns were painted red because the mineral hematite was cheap and easy to add to the paint and it leaves you with a nice rusty read color because it is an iron oxide mineral.

Glass is made by melting down quartz sands.

Gypsum is used for making dry wall.

I guess you're not old enough to have had a crystal radio as a kid.....

Upside -- it didn't take any power, no batteries....

Downside -- all it picked up was crappy AM stations.......

The difference between prayer and masturbation - is when a guy is through masturbating - he has something to show for his efforts.
