Frage Antworten
Cement Limestone is heated with clay
Concrete Cement mixed with sand, (water) and aggregate can be reinforced with steel
Mortar Cement and sand weaker than concrete
Ores Mined, May be concentrated/purified has to be economical to extract typically metal oxides
Metal extraction If less reactive with carbon: extracted by reduction using carbon More reactive than carbon? Electrolysis
Copper extraction Can be extracted by heating (smelting) purified by electrolysis
Aluminium and Titanium extraction Electrolysis extraction >lots of evergy used >many stages in the process Titanium extracted by displacement
Cast Iron 96% iron High strength in compression Brittle Manhole covers, etc.
Steels Low carbon = easily shaped High carbon = hard Stainless steels (with chromium and nickel) = corrosion resistance
Transition metals Advantages Malleable, ductile to heat and electricity
Copper Uses + advantages Electical wiring and pipes Good conductor Malleable yet hard Unreactive with water
Aluminium/titanium Uses/advantages Low density Corrosion resistant hip replacements etc.
Alloys (General) Make harder (different sized atoms disrupt regular structure) Differing properties All metals bond e.g brass, steels, etc.
