Ecertec powder processing technology is comprised of a wealth of experience in specialist development of electroceramic powders. High quality controllable dielectric and ferroelectric powders are produced without the need for exotic or impractical equipment or processes.
High Energy Bead Milling (HEBM) is commonly used for the production of ceramic powders. Ecertec has developed this technology specifically for lead (Pb) based materials, such as PZT, PMN etc. Our processes overcome the traditional powder problems of Pb evaporation losses, compositional variability and control of stoichiometry.
Control of the milling process parameters allows us to control both the compaction and sintering behaviour to ensure optimum ceramic properties.
How you can use our powder technologies.... BACK TO TOP
Services for Volume Powder Producers BACK TO TOP
Ecertec consultants have many years experience of powder technology insertion into volume processing environments. Because we have experience of the device requirements and the commercial constrainsts of the electro-ceramics industry Ecertec process improvements are integrated easily into your processes. Typical advantages are:
Reduced processing time and costs
Improved compositional control and stability
Continous or Semi-continuous process
Reduced batch to batch errors and contamination
Proven technology for both bulk and tape cast producers
Much reduced sintering temperature without the need for additives
Our aim is to inegrate the most appropriate package of technologies into your systems and processes with the minimum of disruption and with the highest degree of flexibility. This may be achieved by:
