Higher melting point aluminum
http://molecularrecipes.com/RyTc/why-does-silicon-nitride-have-a-high-melting-point WebThe elements from Na to Al have metallic bonding - the electrostatic attraction between positively charged metal ions and the delocalised electrons. Sodium forms Na+ ions, therefore 1 electron is lost from each Na atom, whereas aluminium forms Al3+ ions, so 3 electrons are lost per each Al atom. The number of delocalised electrons therefore ...
