Crystal Glass
What is the difference between glass and crystal and diamond?
I've been asking in a shop just looking at jewelry they have and something called my attention, is the model that is made of diamonds / crystals / glasses. So I've been wondering how I can know if a diamond, crystal or glass? You must have the details that a diamond crystal and glass looks like or what kind of difference that is!
It's all about marriage! First Instead, let's start with the definition of what is and is not a crystal. A crystal is any solid with a regular and repeated "the structure of glass." This means that all material atoms are aligned in a regular and repeated. Basically, a crystal structure formed by a unit called "cell" of cells and this is repeated over and over again. Glass is not a crystal as its atomic structure is disordered (but more on that later). The crystals are different in two ways: composition and bonding. Graphite and diamond are the same composition and are crystals, but because the link is a different one is used as "primary" pencils while the other is very difficult (and shiny which is good for rings). The union called on the diamond sp3 hybridization of carbon. This is a Elegant describe the state of the covalent binding of carbon. I will not go into great detail, but suffice to say, the stregth and the directionality of the union, the diamond is hard. Graphite is carbon hexagonal close-packed set, which means that their conditions of servitude in the leaves of a hexagon with weak ties connect the hexagons stacked. These weak bonds between layers allows cutting (slides) with ease it ideal as a writing utensil. Many different types of glass there, but I guess you mean "what is the material commonly called" crystal "? when asked this question. This leads to the glass … I said before the glass is not clear and that is true, but what is known as "crystal" (such as cups and expensive knick-knacks) is actually made of glass, making it one of the most correctly name the objects of all time! The glass can be many compositions, but usually begins as sand (SiO2), soda ash (Na2O) and lime (CaO) so most commercial glass is called soda-lime-silicates. These compounds are mixed and heated to melting. The trick to making a glass is cooled before the merger the atoms align in a crystal. We say that the thermodynamics of cooling Kenetics exceed the crystallization. Thus, after cooling it a material with a non-crystalline atomic structure. Basically, it's like frozen liquid disordered structure in place. As I said, the term "crystal" is referred to material that is actually a glass, but is 25% of lead added to increase the refractive index, which means more light reflected from the surface glass. This makes the glass more brilliant, which I think is attractive to people, though I wonder if it would be so attractive if people knew the amount of lead in the glass! As for telling the difference between them, can do several things, but unfortunately, tend to be destructive. hardness test measures the strength of the joint surface, which is different from most materials. Proof of the difference in heat capacity at phase transitions in differential scanning calorimetry also notice the difference. But the best way is to have trained eye to examine the material under a microscope. You will be able to see the growth crystallographic directions under a microscope that to report on the glass, and if there are none … is a glass. So as you can with it the field of materials science is enormous, but what separates materials usually comes down to how a material is attached.
