why is lithium oxide has a higher melting point compared to Boron trioxide
Answers
Answer:
Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen:
4Li + O
2 → 2Li
2O.
The ground state gas phase Li
2O molecule is linear with a bond length consistent with strong ionic bonding.
VSEPR theory would predict a bent shape similar to H.
The inert capping layer in the Liquid Encapsulation Czochralski process for the production of gallium arsenide single crystalIts usage is also being investigated for non-destructive emission spectroscopy evaluation and degradation monitoring within thermal barrier coating systems.
Molten boron oxide attacks silicates. Internally graphitized tubes via acetylene thermal decomposition are passivated.[
