zinc sputtering targets(Zn)产品概况

Zinc is a silvery white slightly bluish metal, which is brittle at room temperature; It becomes soft at 100-150 ℃; After exceeding 200 ℃, it becomes dry again. Zinc has active chemical properties. In the air at normal temperature, a thin and dense basic zinc carbonate film is formed on the surface, which can prevent further oxidation. When the temperature reaches 225 ℃, zinc oxidizes violently.


Zinc is difficult to burn in the air and emits strong white light in oxygen. There is a layer of zinc oxide on the surface of zinc, which emits white smoke when burning. The main component of white smoke is zinc oxide, which not only blocks the burning of zinc, but also refracts the flame color to form a pale light. Zinc is easily soluble in acid and can easily replace gold, silver, copper, etc. from the solution. The melting point of zinc oxide film is high, but the melting point of metal zinc is very low. So when the zinc sheet is heated on an alcohol lamp, the zinc sheet melts and softens, but does not fall down. It is precisely because of the role of the oxide film. Zinc is mainly used in steel, metallurgy, machinery, electrical, chemical, light industry, military and medical fields.


When the temperature reaches 225 ℃, zinc oxidation is intense. Zinc is easily soluble in acid and can easily replace gold, silver, copper, etc. from the solution. In nature, zinc mostly exists as sulfide. The main zinc-bearing mineral is sphalerite. There are also a small amount of oxide minerals, such as smithsonite, such as smithsonite and hemimorphite.


The chemical properties of zinc are similar to that of aluminum, so the chemical properties of zinc (amphoteric) can usually be inferred from the properties of aluminum.


① Zinc can react with acid and alkali.


② Zinc oxide and zinc hydroxide are soluble in both acid and alkali.
