Difference Between Crystalline and Amorphous

In this blog post, we’re going to talk about the difference is between crystalline and amorphous. We’ll also be talking about how these two substances are formed and why they have different properties. Maybe you’ve heard of them before, or maybe not! Either way, it’s a really interesting topic that I’m sure will teach you something new today. the Major Difference Between Crystalline and Amorphous is that Crystalline is a regular & repeating arrangement of components in a solid having a sharp melting point with definite heat of fusion while Amorphous has an irregular pattern of ions, atoms, or molecules in solids having over range melting point with no definite heat of fusion.

What is a Crystalline?

A crystalline is a type of mineral that has an orderly arrangement of atoms, ions, or molecules. Crystals are usually transparent and have six sides meeting at the corners to form an asymmetrical shape. The most common crystal shapes are hexagonal prism (like granite), the octahedron (like quartz), a tetrahedron (like a diamond).

Crystals can be identified by their cleavage direction – this is where when they break into two planes at right angles to each other. There are many different types of crystals including but not limited to cubic zirconia, opal, agate, amethyst, obsidian.

What is Amorphous?

Amorphous is a word that can be used in many different contexts. It can mean “having no definite shape or form; shapeless” but also it could refer to something like, “not having an agreement about the meaning of words.” The latter definition is what this blog post will be discussing. What does amorphous really mean?

Amorphous substances are characterized by a lack of definite form and shape, and an inability to be crystallized. This is due to the fact that their molecules do not have a regular arrangement or density of atoms. Amorphous solids can flow like liquids but retain their distinct shapes. Examples include sugar, glass, paper, and paint.


Crystals are solids with a regular, repeating arrangement of atoms or molecules while amorphous substances have no such pattern. The two types of matter behave differently under the same conditions because the irregular atomic structure in an amorphous substance can’t arrange itself into a regular pattern like that found in crystals.
