Reaction‐bonded oxide ceramics based on intermetallic compounds are able to compensate the sintering shrinkage completely due to their high increase in volume caused by oxidation. Using low‐pressure injection molding (LPIM) for shaping ceramics avoids needless materials loss and affords the manufacturing of complex formed structures. The combination of both, reaction‐bonded ceramic and LPIM‐processing, offers the manufacturing of ceramic microparts by keeping a high accuracy and replication quality.
