My book says

A thermite reaction is an exothermic reaction, it releases a large amount of heat so that temperature increases up to 3500 °C.

On the other hand, it says the melting point of diamond is 3500 °C.

So my question is whether diamond can by melted in such reaction?

    $\begingroup$ At those temperatures diamond will burn unless you protect to from the thermite and the air. $\endgroup$ – matt_black Sep 22 '16 at 11:17
  • $\begingroup$ I think your book is wrong about temperature generated by thermite. en.wikipedia.org/wiki/Thermite suggests only 2500C for Fe2O3 thermite and Al boils in about this temp. Maybe some alternative version would generate 3500... $\endgroup$ – Mithoron Sep 22 '16 at 13:43
