Crystalline Insulin

            The crystal structure occurs in all classes of materials, with all types of chemical bonds. Almost all existing metal bonding on a polycrystalline state; amorphous or single-crystal metals must be produced synthetically, with great difficulty. Crystal ionic bonds can be formed during solidification of salt, either liquid or condensation of molten solution. Covalent crystals are also very common. An example is the diamond, silica, and graphite. Polymer materials generally will form crystalline parts, but the lengths of the molecules usually prevent complete crystallization. Weak Van der Waals style can also play a role in the crystal structure. For example, this is the type of bond that unites the hexagonal patterned layers on graphite.

Gallium, a metal easily form a large single crystal

            Although the term "crystal" has the meaning specified in the materials science and solid-state physics, in everyday life "crystal" refers to solid objects that show certain geometric shapes, and often bad in the eyes. Various forms of the crystals can be found in nature. The forms of these crystals depend on the type of molecular bond between the atoms to determine the structure, and also the creation of the state of the crystal. Snow flowers, diamonds, and table salt are examples of crystals.

            In any crystal color emitted, bring its own beauty. Twinkle-twinkle crystal light gives luxury and glamor impression. That's why it made ​​crystal jewelry and accesories that charming. Crystals color are very diverse. The colors of the crystals are also following months:

Crystal color corresponding month:

·         January: Pomegranate, a symbol of trust and friendship. The color red is getting increasingly expensive.

·         Feb: Amethyst, often acting on the philosophy of religion. The color is dark purple.

·         March: Aquamarine, soothing.

·         April: Diamond, symbol of love, passion, cheerful.

·         May: Emerald, associated with fertility, the wearer is said to be ageless.

·         June: Pearl, symbol of domestic happiness.

·         July: Red Pomegranate, associated with strength and power.

·         August: symbol of the patron, or protector.

·         September: Patchouli, purportedly believed that the wearer will have attractiveness.

·         Oct: Tourmaline, according to the young at heart.

·         November: Citrine, provide encouragement and hope, brownish yellow color.

·         Desember: Turquisa, give positive energy, the blue color of the sea.

Bismuth Crystal

            Bismuth is a chemical element in the periodic table that has the symbol Bi and atomic number 83. With crystalline trivalent metal has chemical property similar to arsenic and antimony. All types of metal, this element is diamagnetic and the second after the mercury is an element that has the lowest thermal conductivity. Lead-free bismuth compounds are often used as an ingredient in cosmetics and in the medical field.

            Heavy metals such as bismuth harmless elements like Lead, Thallium, and Antimony. Bismuth diamagnetic has high electrical resistance. When it have burned with oxygen, bismuth burns with a blue flame.

            In the earth's crust, bismuth is approximately 2 times more abundant than gold. Bismuth oxychloride is used in the field of cosmetics and bismuth subnitrate and subcarbonate used in the field of medicine.

·         Strong permanent magnets can be made from a mixture of bismanol (MnBi)

·         Bismuth is used in the production of soft iron

·         Bismuth is being developed as a catalyst in the manufacture of acrylic fiber

·         Bismuth has been used in peyolderan, low-toxic bismuth especially for soldering in food processing equipment.

·         As the layers of glass ceramic materials

Kinds of Crystal

            Crystal is a solid atom, molecule, or ion constituent packed regularly and repeatedly widened pattern in three dimensions.

            In general, liquid crystals form when subjected to compaction process. In ideal conditions, the result can be a single crystal, which all the atoms in the solid "attached" to the crystal lattice or similar structure, but, in general, most of the crystals formed simultaneously resulting in polycrystalline solids. For example, most metals that we see everyday are polycrystalline.

            Crystalline structure which is formed from a liquid depends on the fluid chemistry itself, when the solidification conditions, and ambient pressure. Process of forming a crystalline structure known as crystallization.

Bismuth crystal

            Although the cooling process often produces a crystalline material, under certain circumstances the fluid can freeze in a non-crystalline form. In many cases, this occurs because the cooling is too fast so that atoms cannot reach its lattice site. A non-crystalline material commonly called amorphous or glassy material. Such materials are also sometimes referred to as an amorphous solid, although there are clear differences between solids and glasses. The process of forming a glass does not release heat melt types. For this reason many scientists consider glassy materials as liquids, not solids.

            Crystal structure occurs in all classes of materials, with all types of chemical bonds. Almost all existing metal bonding on a polycrystalline state; amorphous or single-crystal metals must be produced synthetically, with great difficulty. Crystal ionic bonds can be formed during solidification of salt, either liquid or condensation of molten solution. Covalent crystals are also very common.

For example, this is the type of bond that unites the hexagonal patterned layers on graphite.

            Most crystalline materials have various types of disabilities crystalographic. The type and structure of these defects can be a great effect on the properties of the material.
