Is the term "carboreduction" interchangeable with "carbothermic reduction"? I am currently studying reactions involving the reduction of metal oxides by carbon at high temperature to produce refractory carbides (such as $\ce{ZrC}$) following equations such as:

$$
\ce{ZrO2 + 3C -&gt; ZrC + 2CO (g)}
$$

I have come across both the following terms for this type of a reaction carbothermic reduction and carboreduction; they appear to be used completely interchangeably. I would like to make sure (as I have not yet found a source to say otherwise) that this is the case in chemistry terminology and not that one may be applied to an equation as above and the other to a similar reaction where the product is actually the pure reduced metal, such as that for iron ore smelting:

$$
\ce{2Fe2O3 + 3C -&gt; 4Fe + 3CO2}
$$
The term "carboreduction" has an IUPAC definition:


  Process in which a metal oxide is reduced in the presence of carbon or a carbon-containing compound.


So technically the term does not require heating and isn't limited to elemental carbon.

Carbothermic definitely implies heating.
