Pure zinc oxide Cream
(Please note this particular zinc oxide is non-nano which is what most people are looking for when it comes to skincare applications among other things.)
“Philosopher’s Wool”, “Chinese White”, and “Flowers of Zinc, ” – these are some of the names given to a compound that’s uses range from rubber to ceramics; concrete to medicine; cigarettes to food; paints to electronics and everything in between. Its official name is Zinc Oxide, and its uses are expanding as fast as technology is advancing. Many of its uses take advantage of its ability to conduct heat, antibacterial and UV-protection properties as well as its ability to act as a binding agent when mixed with other substances.
Zinc Oxide can occur naturally as the mineral zincite. This rare crystal has been found the Franklin and Sterling Hill Mines in New Jersey. These crystals can also be formed artificially and are a natural by-product of smelting zinc. Both natural and synthetic crystals can be colored dark red, orange, yellow and green. However to keep up with a nearly one million tons per year industrial demand for zinc oxide, most is created artificially by several different processes:
The American process involves heating zinc composites (such as the above mentioned by-products of zinc smelting) with carbon in order to create zinc vapor. This vapor then reacts with the oxygen in the air to produce zinc oxide that, as it cools, can be collected. The more common method is the French process. This similar process utilizes metallic zinc heated inside a graphite container that can withstand extreme temperatures.
Specialized laboratory processes can synthesis zinc oxide for various niche applications (such as creating nanowire, thin film, or mass production). The white powdered form can be created by running an electric current through a solution of sodium bicarbonate with a zinc anode inside. The resulting zinc hydroxide gas produced is heated and decomposes into zinc oxide. Extremely pure forms of zinc oxide have exciting applications in nanotechnology. Compatible with well-developed silicon technologies zinc oxide nanowires have potential use in computing, solar energy and beyond.
