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 ]
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]
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
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 borate refers to a family of inorganic compounds consisting of borate of zinc. They are white solids with the formulas 4ZnO·B 2 O 3 ·H 2 O, ZnO·B 2 O 3 ·1.12H 2 O, ZnO·B 2 O 3 ·∼2H 2 O, 6ZnO·5B 2 O 3 ·3H 2 O, 2ZnO·3B 2 O 3 ·7H 2 O, 2ZnO·3B 2 O 3 ·3H 2 O, 3ZnO·5B 2 O 3 ·14H 2 O, and ZnO·5B 2 O 3 ·4.5H 2 O.
Zinc oxide eugenol is also used as an impression material during construction of complete dentures and is used in the mucostatic technique of taking impressions, usually in a special tray, (acrylic) produced after primary alginate impressions. However, ZOE is not usually used if the patient has large undercuts or tuberosities, whereby silicone ...
