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 ...
Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume.
Zinc oxide nanoparticles are nanoparticles of zinc oxide (ZnO) that have diameters less than 100 nanometers. They have a large surface area relative to their size and high catalytic activity . The exact physical and chemical properties of zinc oxide nanoparticles depend on the different ways they are synthesized .
Zinc phosphate is an inorganic compound with the formula Zn 3 (PO 4) 2. This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become ...
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 ferrites are a series of synthetic inorganic compounds of zinc and iron with the general formula of Zn x Fe 3−x O 4.Zinc ferrite compounds can be prepared by aging solutions of Zn(NO 3) 2, Fe(NO 3) 3, and triethanolamine in the presence and in the absence of hydrazine, [1] or reacting iron oxides and zinc oxide at high temperature.
Zinc oxide is used to protect rubber polymers and plastics from ultraviolet radiation (UV). [127] The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. [146] The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production. [147]
Zinc titanate, also known as zinc titanium oxide, is an inorganic compound existing in three major forms: ZnTiO 3 (ZnO-TiO 2), Zn 2 TiO 4 (2ZnO-TiO 2) and Zn 2 Ti 3 O 8 (2ZnO-3TiO 2). It is used as a regenerable catalyst, a pigment and a sorbent of sulfur compounds at elevated temperatures. [1] It is a white powder that is insoluble in water.
