Zn O decomposes into zinc vapor and oxygen at around 1975 °C with a standard oxygen pressure.In a carbothermic reaction, heating with carbon converts the oxide into zinc vapor at a much lower temperature (around 950 °C). The wurtzite structure is most stable at ambient conditions and thus most common.This and other lattice symmetry properties result in piezoelectricity of the hexagonal and zincblende Zn O, and pyroelectricity of hexagonal Zn O.The hexagonal structure has a point group 6 mm (Hermann-Mauguin notation) or C as well as the strong piezoelectricity of Zn O.Our count for Kato has now risen to 39; we added five retraction notices to our count for Kato last month.Zinc oxide is an inorganic compound with the formula Zn O.New S: Nishikido Ryo has been rumored to be dating/have dated: Sawajiri Erika, Aibu Saki, Uehara Takako, and Ishihara Satomi.
This property makes it a technologically important material for many piezoelectrical applications, which require a large electromechanical coupling.
Zn O reacts slowly with fatty acids in oils to produce the corresponding carboxylates, such as oleate or stearate.
Zn O forms cement-like products when mixed with a strong aqueous solution of zinc chloride and these are best described as zinc hydroxy chlorides.
Known p-type dopants include group-I elements Li, Na, K; group-V elements N, P and As; as well as copper and silver.
However, many of these form deep acceptors and do not produce significant p-type conduction at room temperature.
The zincblende form can be stabilized by growing Zn O on substrates with cubic lattice structure.
