Sintering is a critical step in ferrites manufacturing. Sintering of ferrites requires an equilibrium between time, temperature and atmosphere along each phase of the sintering cycle. Improper control during the initial stages of sintering can result in physical problems due to excessively rapid binder removal. Poorly controlled initial stages of heating, or later stages of cooling, can result in stress induced fracture.

Hi Florian,

Thanks for your respond. Do you know what is the recommended rate for burn off zone? Sintering in vacuum atmosphere. Previously have no problem. Thanks

Adopt the low heating rate procedure and also optimize the sintering time.

Why after done sintering, discoloration occur? Sintering at air atmosphere.
