Crystallize Definition (Crystallization) By Anne Marie Helmenstine, Ph.D. Crystallize Definition: crystallization is the slow precipitation of crystals from a solution of a substance. Crystallization can also refer to the solid-liquid separation and purification technique in which mass transfer occurs from the liquid solution to a pure solid crystalline phase.

Crystallization In this phase of crystallization, crystal growth is initiated with contact. The contact can be between the solution and other crystals, a mixer blade, a pipe, a vessel wall, etc. This phase of crystallization occurs at lower supersaturation (than primary nucleation) where crystal growth is optimal.

- Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer.

CRYSTAL • CRYSTAL (noun) The noun CRYSTAL has 6 senses: 1. a solid formed by the solidification of a chemical and having a highly regular atomic structure. 2. a crystalline element used as a component in various electronic devices. 3. a rock formed by the solidification of a substance; has regularly repeating internal structure; external plane faces.

- He evaporated a solution of Ammonium Cyanate to produce Urea. Organic Chemistry has undergone a substantial change since then. There are well over a million synthetic organic compounds. Organic Chemistry is defined as the Chemistry of Carbon and its compounds. Carbon is a Lego( like element. I use the analogy Lego’s because these atoms tend to form bonds with themselves creating different shapes. Like the two below, octane on the left and a steroid precursor on the right. The shapes are created by the chemical property of carbon to form 4 bonds.

Crystal Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Examples of polycrystals include most metals, rocks, ceramics, and ice. A third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. crystal is a solid where the atoms form a periodic arrangement. (Quasicrystals are an exception, see below .). Not all solids are crystals. For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure.

crystalloid 1. resembling a crystal. 2. a substance whose particles are smaller than those of a colloid, form a true solution, and are therefore capable of passing through a semipermeable membrane, as in dialysis. The physical opposite of a crystalloid is a colloid, which does not dissolve and does not form true solutions.

Theory of crystal formation complete again Crystallization is the formation of a solid ordered substance, such as happens when water freezes. In nature, crystals are mostly formed from ions which are dissolved in water, as for example in the formation of shells or bone. This involves the clustering of ions into increasingly large nuclei, until a crystal is formed when a certain size is reached. However, the details of this growth process have been the subject of discussion for many years.

Organic chemistry Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.or molecules showing color, the carbon atoms are in black, hydrogens in gray, and oxygens in red. In the line angle representation, carbon atoms are implied at every terminus of a line and vertex of multiple lines, and hydrogen atoms are implied to fill the remaining needed valences (up to 4).

Crystal structure Crystal structure In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice.

- A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an ordered pattern extending in all three spatial dimensions. Ionic crystals can form upon solidification of salts, either from a molten fluid or upon crystallization from a solution.

- Crystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution. solution that has as much solid dissolved in it as it can possibly contain is called a saturated solution. As the saturated solution is allowed to cool, the solid will come out of the solution and crystals will start to grow.

- An impure solid in: (A) cold solvent in which it has low solubility, (B) solvent that has been warmed up to dissolve all of the solid, and (C) solvent that has cooled down to the original temperature. The crystallized solid is now pure, while the impurities remain in solution. Recrystallization. Recrystallization is the preferred method for purification of organic solids. The technique can be used for large or small quantities of materials, and is usually very effective and efficient. The most important aspect of the recrystallization technique is the selection of the solvent.

The Metric System: Distance and Mass The metric system of measurement is far easier than the English system that most Americans are accustomed to. This is mainly due to the fact that all units are in multiples of 10s, so it is easy to do calculations in your head. Also, working within the metric system, one never has to convert units.
