White brass deposits containing 85% zinc and 15% copper have also been plated to a limited extent , mainly as an undercoating for chromium during the nickel shortage, but they did not prove fully satisfactory. 

Below silt accumulations on copper, brass, and cupronickel heat exchangers, a layer of bluish-white copper carbonate often forms (Figs. 4.14 and 4.15). 

Figure 4.6 A thin, glassy layer of predominantly manganese oxide on the internal surface of a brass condenser tube. The many white spots are pits at fractures in the manganese layer.

Figure 13.8 A brass tube showing plug-type dezincification. The white patch above the plug on the external surface was caused by dissolved solids, concentrated by evaporation of water leaking through the porous dezincified plug.

Gruehn et al. [42] have reported on the isomorphy between modifications of LaTa309 and CeTajOg. Both contain trivalent lanthanide ions. The former is white, the latter is orange (P-modification), brass (O-modification) or yellow (M-modification). These colors are due to Ce(III)-Ta(V) MMCT absorptions, the Ce(III) and tantalate chromophores absorbing only in the ultraviolet. No doubt there are many more examples of this type in the literature. 

Bluish, shimmering, brittle, relatively reactive metal. Is guite guickly covered with a protective oxide layer, which is why iron is treated with zinc With copper, forms the popular alloy brass, which was already known in antiquity. Used in batteries and as a stabilizer in plastics. Zinc oxide is used as a white pigment Zinc ions are essential to all life forms, e.g., as a component of alcohol dehydrogenase and many other enzymes. Hence human beings (70 kg) carry about 2.3 g (half as much as iron). 

When in 1976, commissioned by the architect Felix Noviakov, Kosmatschof designed four sculptures in white porcelain and brass for the Soviet embassy in Mauritania, he was not permitted to travel to the site for the assembly of the elements. He had to report... 

Lead azide is an explosive solid that can be detonated by shock (or by heating to 350 °C), while sodium azide exists as stable white crystals that decompose smoothly on heating (unless allowed to react with extraneous material). Why are heavy metal azides so explosive Why are lead azide detonators not sheathed in copper or brass ...
