A solid is a substance that is not liquid. Its crystalline structure is the result of crystallization. This article provides an overview of solids. We will cover the Molecular solid, Amorphous solid, and Crystalline solid. Each of these is important to know. The article will also explain the relationship between these different types of solids. You can use the links below to learn more about each of these types. Read this article if you’re interested in understanding the properties of different solids.
Molecular solids
A molecular solid is a solid made up of discrete molecules, bonded together by van der Waals forces, dipole-dipole interactions, or quadrupole interactions. The structure and properties of these materials are governed by a variety of different forces. In this article, we will explore three different types of molecular solids. These solids are commonly used in engineering, physics, and nanoscience.
Noncrystalline solids
Journal of Noncrystalline Solids (JNCS) is a peer-reviewed scientific journal that specializes in research on amorphous materials. It was founded in 1968 and is published by Elsevier. Editor-in-chiefs are Barrett G. Potter, Edgar Dutra Zanotto, and Josef W. Zwanziger. Noncrystalline solids are an important area of study in physics, chemistry, and materials science.
Amorphous solids
Amorphous solids are rigid but disordered assemblies of atoms. They share many mechanical properties with liquids and gases, but they lack a thermodynamically stable microstructure. A general theory of amorphous solids is necessary to understand their behavior. Here is a brief review of the theory’s key concepts. Amorphous solids are often referred to as amorphous because their rigidity is determined by the amount of disorder.
Crystalline solids
Crystals are materials with highly ordered microscopic structures that form a lattice. These solids are made up of molecules called atoms and protons arranged in a hexagonal pattern. If you’ve ever wondered what a crystal looks like, then you’ve come to the right place. Crystals are a class of solids that belong in the class of crystalline materials. Here’s how crystals form.
Semicrystalline solids
Unlike amorphous polymers, which soften slowly as the temperature rises, semicrystalline solids change from solid to liquid quickly. Semicrystalline plastics have strong intermolecular forces and make for very tough plastics. Semicrystalline plastics are generally high-strength, with low coefficient of friction, and excellent chemical resistance. Polypropylene and polyethylene are examples of semicrystalline plastics. However, polyethylene does have a higher melting point and is not a good choice for welding.
Molecular network solids
Molecular network solids are solid compounds composed of nonmetals. These substances have chemical bonds and are held together by attractive forces. Diamond, for example, is a network solid. As the name implies, it is made up of many atoms linked together by chemical bonds. Carbon exists as a single element at room temperature and in three different forms: diamond, aragonite, and graphite. Molecular network solids are similar to crystals, but differ in one key way.
