Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...
Z-Cote is a commercial zinc oxide line [1] manufactured and owned by BASF. [2] Due to Z-Cote's photo-protective properties it is commonly used in personal care products and sunscreens. It is available in nano, non-nano, coated and uncoated forms. [ 3 ]
For corrosion protection in nuclear reactors of the light water reactor design, depleted zinc oxide is produced by first passing diethylzinc through an enrichment centrifuge. The pyrophoricity of diethylzinc can be used to test the inert atmosphere inside a glovebox. An oxygen concentration of only a few parts per million will cause a bottle of ...
Solutions of sodium zincate may be prepared by dissolving zinc, zinc hydroxide, or zinc oxide in an aqueous solution of sodium hydroxide. [2] Simplified equations for these complex processes are: ZnO + H 2 O + 2 NaOH → Na 2 Zn(OH) 4 Zn + 2 H 2 O + 2 NaOH → Na 2 Zn(OH) 4 + H 2
It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide ("zinc white"), zinc sulfide, and white lead. [1]
Zinc oxide is used to protect rubber polymers and plastics from ultraviolet radiation (UV). [125] The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. [144] The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production. [145]
An early example of zinc white's use in painting [1]: 183 Zinc white is an inorganic pigment composed of zinc oxide that has been used by painters since the late eighteenth century. [1] Alongside lead and titanium white, it is among the three most prominent white pigments that are commercially available today. [1]
Zinc oxide eugenol (ZOE) is a material created by the combination of zinc oxide and eugenol contained in clove oil. An acid–base reaction takes place with the formation of zinc eugenolate chelate. The reaction is catalysed by water and is accelerated by the presence of metal salts.
