Annealing is a term used in metallurgy as well as in Biotechnology. As far as metallurgy is concerned, it is a heat treatment process whereby a metal is heated to a specific temperature much below its melting temperature, held for a specific time and then allowed to cool slowly. This is mainly to impaqrt some desired property in the material.
Sintering is an agglomeration technique whereby particulate materials are heated much below the melting point until the particles fuse together by atomic fusion.
Calcination is a process of effecting thermal decomposition or phase transition in agglomerated material by heating below the melting point.
