Crystal A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.nhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid. The flat faces (also called facets) of a euhedral crystal are oriented in a specific way relative to the underlying atomic arrangement of the crystal: They are planes of relatively low Miller index.

- In summary, a crystal is any solid material with its atoms organized in a repeating pattern. There are four types of crystals. Covalent crystals occur when the atoms form strong, covalent bonds. Such crystals, like diamonds, are very tough. Ionic crystals, like table salt, are hard and stable but are made of atoms connected by electrical charges. Metallic crystals are formed from metal elements and conduct electricity well. Molecular crystals, like rock candy, are formed through hydrogen bonds and are generally weak and have a low melting point.

Crystal A crystal structure (an arrangement of atoms in a crystal) is characterized by its unit cell, a small imaginary box containing one or more atoms in a specific spatial arrangement. The unit cells are stacked in three-dimensional space to form the crystal.nhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid. The flat faces (also called facets) of a euhedral crystal are oriented in a specific way relative to the underlying atomic arrangement of the crystal: They are planes of relatively low Miller index.

Definition and Symptoms of Chronic Kidney Disease A kidney stone occurs when substances in the urine form crystals. Kidney stones can be large or small. Large ones can damage the kidneys; small ones may be able to pass in the urine. Because crystals have sharp edges, passing even small stones can be very painful. Treatment depends on what the stones are made of.

Crysts, Blasts and Clasts - Terminology of Large Particles Crysts. The -cryst suffix refers to grains of a crystalline mineral. A-cryst can be a fully formed crystal like your typical garnet, or it can be an irregular grain that, even though its atoms are all in rigid order, has none of the flat faces that mark a crystal.

Crystal Retention in Renal Stone Disease: A Crucial Role for the Glycosaminoglycan Hyaluronan? The precipitation of poorly soluble calcium salts (crystal formation) in the kidney is the inevitable consequence of producing concentrated urine. HA is a major constituent of the extracellular matrix in the renal medullary interstitium and the pericellular matrix of mitogen/stress-activated renal tubular cells.

- Jupiterimages/Polka Dot/Getty Images. Ear crystals (otolith or otoconia) are tiny calcium carbonate/calcite crystals embedded in the gelatinous otolithic membrane in the inner ear. The otolithic organs (the utricle and the saccule) are what enables you to discern which way is up even when your eyes are closed.

Gout Basics of gout. Gout is a disease that causes sudden severe episodes of pain and tenderness, redness, warmth and swelling (inflammation) in some joints. Gout is a dramatic example of a type of arthritis called crystal arthritis, sometimes called microcrystalline arthritis because the crystals are very small.The crystals form in the joint space. As the body tries to remove the crystals, a painful inflammation occurs.ric acid usually is dissolved in the blood and passes through the kidneys into the urine. In people with gout, the uric acid level in the blood is so high that uric acid crystals are deposited in joints and other tissues.
