Lead-tin-yellow: PbSnO 4 or Pb(Sn,Si)O 3. Titanium pigments. Titanium yellow (PY53): NiO·Sb 2 O 3 ·20TiO 2; Tin pigments. Mosaic gold: stannic sulfide (SnS 2). Zinc pigments. Zinc yellow (PY36): zinc chromate (ZnCrO 4), a highly toxic substance with anti-corrosive properties which was historically most often used to paint over metals.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...

Zinc, cadmium and mercury form a large range of alloys. Among the zinc containing ones, brass is an alloy of zinc and copper. Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium and sodium. [11]
Lithium oxide – Li 2 O; Magnesium oxide – MgO; Potassium oxide – K 2 O; Rubidium oxide – Rb 2 O; Sodium oxide – Na 2 O; Strontium oxide – SrO; Tellurium dioxide – TeO 2; Uranium(IV) oxide – UO 2 (only simple oxides, oxyhalides, and related compounds, not hydroxides, carbonates, acids, or other compounds listed elsewhere)
Tin is most commonly alloyed with copper. Pewter is 85–99% tin, [97] and bearing metal has a high percentage of tin as well. [98] [99] Bronze is mostly copper with 12% tin, while the addition of phosphorus yields phosphor bronze. Bell metal is also a copper–tin alloy, containing 22% tin.
The zinc content can vary between few % to about 40%; as long as it is kept under 15%, it does not markedly decrease corrosion resistance of copper. Brasses can be sensitive to selective leaching corrosion under certain conditions, when zinc is leached from the alloy (dezincification), leaving behind a spongy copper structure. Nordic Gold
