Previously, the zinc oxide used as white pigment should be called white zinc or zinc flower (a fine powder after condensation of zinc vapor page). In normal conditions zinc oxide fine white powder, when heated above 3000C, it turns yellow (after cooling, the white back)

Each year the rubber industry in the world consumes about 2 to 2.5 million tons of fillers functions, of which about 600 to 700 thousand tons of industrial minerals (predominantly black soot).

Zinc is a metallic element; it is the symbol Zn and chemical number is 30. It is the first element in group 12 of the periodic table of elements. Zinc, on a certain aspect, nature study hioa like magnesium ions because of their similar size and have common oxidation state is only +2. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. Zinc ore is mined most is Sphalerit, a zinc sulfide. The largest mines are in Australia, Canada, the United States. Zinc production includes ore flotation, calcination, and finally working with electric current.

The cooling system is a very important role for electronic devices. High temperatures can degrade the performance of materials or damage them and also to stop the electronic devices when they are active.

News from the Center for Materials Technology (Institute of Applied Technology) said the center's scientists have studied, the successful application of manufacturing technology active zinc oxide as raw material production for many industries such as rubber, construction ceramics, animal feed, cosmetics ...
