ZnO was prepared in olden days by burnin zinc by alchemists.....and alchemy was considered as part of philosophy.....as no science exhisted then......and moreover the prdct was white and wooly...so it is called philosophers wool
Zinc oxide is also called zinc white, calamine, philosopher's wool, Chinese white, and flowers of zinc. (Source: Wikipedia)
2 Zn + O2 = 2 ZnO (zinc oxide, a white powder)
Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
1. Heating zinc oxide at approx. 2 000 0C this compound is thermally decomposed in oxygen and zinc. 2. Zinc oxide can be reduced with carbon to obtain zinc and oxygen: ZnO + C = Zn + CO
Zinc oxide is made through a process called the French process or indirect process. In this method, zinc metal is heated and vaporized, then reacts with oxygen in the air to form zinc oxide. The vapor is then cooled and solidified into a powder. This powder is then further processed and purified to obtain the final zinc oxide product.

The compound ZnO is called zinc oxide.
The compound formed when zinc joins with oxygen is called zinc oxide.
2 Zn + O2 = 2 ZnO (zinc oxide, a white powder)
In English language: zinc oxide. Of course in other languages the name is different.Technically it would be zinc (II) oxide, but +2 is by such a margin the most common oxidation state for zinc that it's usually just called "zinc oxide."
That would be zinc oxide.

Zinc can be obtained from zinc oxide by a process called reduction. This involves heating zinc oxide with carbon or carbon monoxide at high temperatures to produce zinc vapor, which can then be condensed to form solid zinc. This method is commonly used in industrial processes to obtain zinc from zinc oxide.
[metal] oxide is the result. Iron oxide is called rust. Zinc oxide is called . . . zinc oxide which is a skin and wound soothing ointment.

This is an oxidation-reduction reaction. The carbon reduces the zinc oxide to zinc and the zinc oxide oxidises the carbon to carbon dioxide. It can also be called a displacement reaction, as the carbon displaces the zinc from its oxide.
