Information @ a Glance

 General
  • The word crystals originates from the Greek word "Krystallos" meaning clear ice, and once referred particularly to quartz, rock crystal.
  • In chemistry and mineralogy, a crystal is a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions.
  • Most metals encountered in everyday life are polycrystals. Crystals are often symmetrically intergrown to form crystal twins.

Growth

  • Crystal growth is a complex process. The quality of the grown crystal depends on many macro- and microscopic effects.
  • Crystals of calcium oxalate monohydrate compound is a basic component of most renal stones.
  • COM(calcium oxalate monohydrate) crystals were grown in urine, in different gels (by the counter diffusion method) and by direct pouring of reagent solutions together.

Process

  • Cavan Crystal Manufacturing:Raw materials are batched to Cavan Crystal’s own specification and placed in clay pots.
  • The Czochralski Manufacturing:This was developed for the growth of single crystal aluminum oxide in plate form for transparent armor applications.
  • The process of forming a crystalline structure from a fluid or from materials dissolved in the fluid is often referred to as crystallization.
  • Crystallography is the study of the formation processes that produce crystals, and of the structural and identifying details of crystals.

Applications

  •  Crystals are used in: Cameras, DataLogging, Digital audio, ISDN Gateway, HomeBanking/Shopping.
  • The native gallium nitride(GaN) crystal is used for the development of ion sensors.
  • The quartz crystal microbalance (QCM) technique has been shown to play a key role in elucidating various aspects of Biomacromolecular recognition reactions.
  • The adsorption of radioactiveCs13 technique might be useful in detecting defective quartz crystals without destructive testing.

Market

  • Ceramic Growth market estimates 2000 market to be $207 million, which includes captive markets and imports, but excludes exports.
  • The market is expected to grow modestly at an annual average growth rate (AAGR) of 8.4% in current dollars
    Piezoelectric ceramic elements constitute 97% of the combined market;i.e., $200 million in 2000 and reaching
    $294 million in 2005.
  • A Country is well-named as the "land of crystals". With 70% of the national reserve of the precious material, it produces 80% of China's crystal products.
  • The Taiwanese market for quartz crystals is generally dominated by Japanese companies.
