a·mor·phous
(ă-mōr’fŭs), 1. Without definite shape or visible differentiation in structure. 2. Not crystallized.
What do you mean by amorphous form?
Amorphous forms are, by definition, non-crystalline materials which possess no long-range order. Their structure can be thought of as being similar to that of a frozen liquid with the thermal fluctuations present in a liquid frozen out, leaving only “static” structural disorder.
What is an example of something that is amorphous?
Unlike a crystalline solid, an amorphous solid is a solid that lacks an ordered internal structure. Some examples of amorphous solids include rubber, plastic, and gels. Glass is a very important amorphous solid that is made by cooling a mixture of materials in such a way that it does not crystallize.
What is Morphous and amorphous?
The first and most common type, known as crystalline or morphous, has regular crystal lattices, or long-range order. These solids are stabilized by the regular pattern of their atoms. … Amorphous solids, on the other hand, are rigid, but they lack repeated periodicity or long-range order in their structure.
What is amorphous carbon used for?
Amorphous carbon nanocomposites
On the basis of their superior and unique properties, these materials have been used in various applications for textile, plastic, and health-care industries as well as in the fields of gas and water filtering, electrical applications, and food packaging.
What does amorphous mean as it is used in a sentence?
Definition of Amorphous. having no clear shape or form. Examples of Amorphous in a sentence. 1. Because the painting was amorphous, I had no idea what it represented.
How do you use the word amorphous in a sentence?
Amorphous sentence example

- Amorphous titanium oxide may be obtained in a pure form.
What makes amorphous solid shapeless?
An amorphous solid is a solid whose atoms are not in a regular crystalline pattern. The word amorphous comes from the Greek word ámorphos, which means “shapeless.” When matter is in a solid form, it may take the form of an amorphous solid depending on its molecular structure and how it was cooled.
What is not amorphous?
Crystalline solids have regular ordered arrays of components held together by uniform intermolecular forces, whereas the components of amorphous solids are not arranged in regular arrays. Rubber is not an amorphous substance.
What is the cause of amorphous Urates?
The formation of amorphous urate crystals can be caused by a combination of factors, including a diet rich in meat, decreased urine volume or a condition that acidifies urine such as chronic diarrhea. They are also present in individuals who have gout or during chemotherapy.
What causes amorphous phosphates in urine?
In most instances the precipitation of crystals of calcium oxalate, uric acid, triple phosphate, calcium phosphate and amorphous phosphates or urates is caused by transient supersat- uration of the urine, ingestion of foods, or by changes of urine temperature and/or pH which occur upon standing after micturition.
What does it mean if you have amorphous crystals in urine?
The presence of amorphous crystals is generally of little clinical significance. Their formation is caused by a combination of factors, including decreased urine volume combined with changes in urine pH and often the presence of large quantities of uric acid (meat consumption), or calcium (dairy products) in the diet.
Can people be amorphous?
of no particular kind or character; indeterminate; having no pattern or structure; unorganized: an amorphous style; an amorphous personality.
Are minerals amorphous?
i. Amorphous materials are non-crystalline, that is they lack long-range regularity in their atomic structure. By definition they cannot be minerals. Nevertheless, some natural amorphous substances have been accepted as minerals.
What is amorphous blob?
The Amorphous Blob is, as its name suggests, a giant shapeless blob with no notable features.
What is the amorphous form of carbon?
In mineralogy, amorphous carbon is the name used for coal, carbide-derived carbon, and other impure forms of carbon that are neither graphite nor diamond.
What is the difference between crystalline and amorphous solids?
Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures.
What are the two amorphous carbon?
However, coke, charcoal, coal and lamp-black are amorphous forms of carbon.
Is coke amorphous form of carbon?
Charcoal, carbon black, and coke are all amorphous forms of carbon. Charcoal results from heating wood in the absence of oxygen. … Coke is a more regularly structured material, closer in structure to graphite than either charcoal or carbon black, which is made from coal.
