Can Diamond be melted in thermite reaction?

[Aafia]

My books says

Thermite reaction is an exothermic reaction, it release large amount of heat so that temperature increases upto 3500°C

On the other hand it is written

Melting point of diamond is 3500°C

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

 

[Borek]

Chemically: what is diamond? What will happen in the presence of the oxidizing agent?

It's probably likely that the molten iron can fuse with the diamond to form some steel if it did melt. Another possibility is for the aluminum oxide to form aluminum oxycarbides with formulas such as Al2OC or Al4O4C
