Technology

Our proprietary lead-free technology enables us to deliver innovative and differentiated solutions.

Lead-free Piezoelectric Materials

A material substance (powder) that has electrical properties that cause charge transfer when pressure is applied,

and that can be electrically moved to achieve mechanical functions.

Advanced piezoelectric materials applied to microelectromechanical components (MEMS), thin films or wafer coatings, etc.

Lead free piezoelectric meterial with conventional piezoelectric ceramic material

BNT forms a tetragonal solid solution with (Bi,K)Ti03[BKT], and in the composition of 0.78BNT to 0.22BKT,

there is a Morphtrophic Phase Boundary (MPB) where Rhombohedral structures and Tetragonal structures exist together.

It has good piezoelectric properties in this area.

→ PZT-based ceramics with a high firing temperature of 1200℃ or higher are subject to rapid volatilisation of PbO at 1000℃ or higher, resulting in environmental pollution and poor reproducibility of composition. The low-temperature sintering method has a low melting point of about 960℃ when manufacturing laminated ceramics with internal electrodes sintered together, and pure Ag

electrodes with low price can be used, which can replace relatively expensive Ag/Pd electrodes containing a lot of Pb. Pb-rich Ag/Pd electrodes, which are relatively expensive, can be replaced to increase price competitiveness.
