Details:

Zinc oxide is an oxide of zinc.Difficult to dissolve in water, soluble in acids and strong bases.Zno is a kind of common chemical additives, widely used in plastic, Portland products, synthetic rubber, lubricating oil, paint coating, ointment, adhesives, food, battery, flame retardants, and other products.Zinc oxide of the band gap and the exciton binding energy is larger, high transparency, has excellent luminescent properties under normal temperature, liquid crystal displays, in the field of semiconductor thin film transistor, light-emitting diodes, and other products are used.In addition, zinc oxide as a kind of nanometer material also began to play a role in related fields.

Zinc oxide production factory mainly concentrated in liaoning (dalian), shandong (weifang), hebei (zhonghan, xingtai), jiangsu, zhejiang and other places, the production of zinc oxide with 99.7% content is given priority to, commonly known as 997 (99.7) zinc oxide.In recent years, nano-zinc oxide has grown rapidly and has become more and more widely used with its excellent nano-characteristics.

Development brief history editor

Humans have long learned to use zinc oxide for paint or for external use, but humans have found it hard to trace the history of zinc oxide.[1]

The Romans learned to use copper and zinc, zinc oxide, to make brass as early as 200 BC.The zinc oxide is turned into zinc vapor in the shaft furnace and rolled into the flue.Dioscorides has also been introduced.[1]

A drug that was later identified as zinc oxide was used to treat eye diseases and trauma in the ancient Indian medical book, chakarabasan.In the first century AD, Greek physician dioscorides also mentioned zinc oxide as a ointment.Avicenna described zinc oxide as the drug of choice for various skin diseases, including skin cancer, in the "return cure" completed in 1025.People no longer use zinc oxide for skin cancer, but are still widely used to treat other common skin conditions.[1]

Since the 12th century, indians have known zinc and zinc and began to smelt the zinc in its original way.Zinc smelting was introduced into China in the 17th century.In 1743, Bristol, England, established the first zinc smelting plant in Europe.[1]

Another major use of zinc oxide was used as a paint, which became watercolor for the first time in 1834, but it was difficult to dissolve in oil.But soon the problem was solved by the new zinc oxide production process.In 1845, leclerc began a large-scale production of zinc and white oil paints in Paris, and by 1850, zinc oxide became popular throughout Europe.The purity of zinc oxide is so high that by the end of the 19th century, some artists painted with zinc and white as the base color, but these paintings have been cracked for hundreds of years.[1]

In the second half of the 20th century, zinc oxide was used in the rubber industry.In the 1970s, the second most common use of zinc oxide was in copier paper additives, but in the 21st century, zinc oxide as a copy paper additive has been eliminated.[2]

The team, led by professor yan yan of the university of island root, synthesized zinc oxide particles, which are about 10 nanometres in diameter, and have been specially treated to make the particles have the properties of fluorescent substances.The nanoparticles have a stable glow, which lasts more than 24 hours, but production costs less than 1 percent of green fluorescent protein.[3]

On November 1, 2008, the researchers fed the mice a protein that combined the particles to produce glowing images of the particles in the mice.[3]

On November 18, 2008, the university of Japan announced the development of a zinc oxide nanoparticle that glows with light and is stable and safe and can be used in cutting-edge medical fields.[3]
