What is the difference between sintering and calcination?

Sintering is a process of compacting material using both pressure and relatively high temperature which is usually bellow the melting temperature. Calcination is a thermal treatment of solids which aims to heat the material at very high temperature in the absence of air or oxygen (or at least under no gas flow).
