During sintering, fine-grained ceramic or metallic materials are heated up at a temperature below the melting temperature of the main components. The shape of the workpiece remains intact. The material condenses and shrinks. A green body is formed which solidifies by temperature. The sintered product only then gets its final properties such as hardness, strength or temperature conductivity. The sintering shrinkage is taken into account during the construction of the restoration – the workpiece is milled larger by the shrinkage factor.

The induction furnace CEREC SpeedFire combines the processes of sintering and glazing in one compact, user-friendly device. This makes it possible to use all the strengths of zirconium dioxide also for a chairside treatment.The CEREC SpeedFire reaches a maximum heating rate of 300 ° C per minute – no preheating or holding temperatures are necessary. Its induction technology ensures a perfectly homogeneous temperature distribution.

The extremely short sintering times are determined by the dry milling of the pre-sintered material. A drying process of several hours is not necessary. Its dimensions make the CEREC SpeedFire a compact device that fits in any practice.

CEREC SpeedFire can process CEREC Zirconia as well as CEREC Zirconia meso, CELTRA DUO, and all CEREC Blocs. Furthermore, the furnace is authorised to process IPS.emax CAD (by Ivoclar Vivadent) and VITA Suprinity (by VITA Zahnfabrik).
