a) 2.8 MB b) K , Na , Ca , Al , Ti Al2O3 + Na2AlF6 ( 960–970°С) Al2O3 = Al(3+) + AlO3(3-) - melt Al(3+) +3e(-) = Al(0) - Kat 4AlO3(3-) -12e = 2Al2O3 + 3O2 - An 2Al2O3 = 4Al + 3O2 c)They lose 7s2 electrons and one by one or with 6d or with 5f shells d) Yttrium Aluminium Garnet , used in Nd:YAG laser
