Applications

Cerium dioxide is mainly for polishing agent of lens. Rare earth polishing powder get wide applications in polishing of  camera, teletube, spectecles glasses, which is also for glass industry.

In glass industry, cerium dioxide combine with titanium dioxide, which make glass show yellow. it use for glass decolorizing, which have high temperature stability, low cost and nonabsorption of visible light and other advantages. Additionally cerium(IV) oxide add into glass for building and automotive glass, which can reduce light transmittance of ultraviolet light.

Ceric dioxide is raw material for production of rare earth luminescent material. It use as activating agent in luminescent material rare earth trichromatic phosphor of energy saving lamp and fluorescent powder of indicator light and radiation detector.

Cerium(IV) oxide is raw material in ceramic glaze and electronic industry as infiltration agent of piezoelectric ceramics. It is also as sensitizer of semiconductor material, advanced pigment and photosensitive glass, purifier of automobile exhaust.

Chlorine Dioxide

Chlorine dioxide is a chemical compound. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleaching. It is used in the electronics industry to clean circuit boards, in the oil industry to treat sulfides and to bleach textile and candles. Nowadays chlorine dioxide is used most often to bleach paper. It produces a clearer and stronger fiber than chlorine does. Chlorine dioxide has the advantage that it produces less harmful byproducts than chlorine. It can be used as oxidizer or disinfectant. It is a very strong oxidizer and it effectively kills pathogenic microorganisms such as fungi, bacteria and viruses. It also prevents and removes bio film. As a disinfectant and pesticide it is mainly used in liquid form. It can also be used against anthrax, because it is effective against spore-forming bacteria. Chlorine dioxide gas is used to sterilize medical and laboratory equipment, surfaces, rooms and tools.

Copper

Copper is a ductile metal, with very high thermal and electrical conductivity. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Copper compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris. Decorative art prominently features copper, both by itself and as part of pigments. Copper(II) ions are water-soluble, where they function at low concentration as bacteriostatic substances, fungicides, and wood preservatives. In sufficient amounts, they are poisonous to higher organisms; at lower concentrations it is an essential trace nutrient to all higher plant and animal life. The main areas where copper is found in animals are tissues, liver, muscle and bone.
