aluminium has greater tendancy to bind to oxygen than carbon,so it cannot be extracted

Why alumina is stronger than aluminium?
because its well hard
Why scientists in 1800 could not extract aluminium from alumina?
The necessary technological conditions did not exist.
What is the difference between alumina hydrate and alumina trihydrate?
Nothing... Alumina hydrate has many names, alumina trihydrate being one of them. The other names are as follows: Aluminum hydrate; Aluminum trihydrate; Aluminum (III) hydroxide; Amorphous alumina; Trihydroxyaluminum
What alloys is aluminum used for?
We use aluminium to make alloys. Alumina is a example.
How is aluminum extracted?
'''Extraction Process''' The principle ore of aluminum is bauxite, a reddish clay-like ore rich in alumina is usually mined by open cut technique. Aluminium is then extracted by electrolysis at a reduction plant, or smelter. The ore is first converted into pure alumina by the Bayer Process which involves heating in caustic soda. The aluminum trihydrate dissolves leaving a residue of insoluble iron and titanium oxides called red mud. The aluminum trihydrate is dried to produce alumina which is electrolysed in molten cryolite because the aluminum oxide has too high a melting point to electrolyse on its own. Then a powerful electric current is run through the liquid to separate the aluminum from the oxygen. As a result, the molten aluminum sinks to the bottom of the pots.
What metal is extracted from alumina?
