1

Iron Ore

Refined by reduction in blast furnace, molten iron in blast furnace called pig iron.

2

Three Ways of Making Steel

Basic Oxygen Furnace
Open-Hearth Furnace
Electric Arc Furnace

3

Alloys

Mixture of two or more metals.
Melting point of alloys are LOWER than its components' melting points
Hardness increases in alloys
Size of crystalline particles determine physical properties of alloy (cooled slowly=larger crystals)

4

Common Alloys

Brass: copper and zinc
Bronze: copper and tin
Steel: controlled amounts of carbon, manganese, sulfur, phosphorus, and silicon, alloyed with nickel and the chromium
Sterling silver: alloyed with copper

5

Metalloids

Form ionic or covalent bonds
Semiconductors

6

Properties of Metals

Metallic Luster
Conduct heat and electricity
Malleable (can form sheets)
Ductile (can form wires)
Silvery (most)
Insoluble w/o chemical change/in typical solvents
