Monocrystals vs. Crystals: Understanding the Difference

[Petar Mali]

Can I say that monocrystals, polycrystals,crystalline ... are types of crystals? What is the difference between monocrystal and crystal? I don't see any difference in definition?! In statistical mechanics for example if you say crystal you don't mean crystalline.

Thanks for your answer

Hi,
Crystalline: Some thing made of crystals.
Monocrystal: One/single crystal.
Polycrystals: more than one crystals.

Hi,

Monocrystal: One/single crystal.

So for you monocrystal=1 crystal

Why you don't say then just crystal!

Look at my question

Can I say that monocrystals, polycrystals,crystalline ... are types of crystals?

monocrystals and polycrystals comes under the crystal. It is not nice to say types of crystals. May be some people get confused with crystal system/classes.
You can say monocrystal as crystal. Saying monocrystal is more specific.
Where you want to say ? Give some more information please.
1 crystal mean= only one crystal (generally you cannot get 1 crystal).
monocrystal is equivalent to = a material whose structure is crystalline and has only one crystal structure.
