[Innovation] - Codex International fully committed to "Lead free materials”

The RoHS concept (Restriction of the use of certain Hazardous Substances) since 2006, requires that many electrical and electronic equipment must no longer contain a concentration by atomic weight of more than 0.1% of Pb, Me, Cr (hexavalent) etc., because of their danger to the environment.

Codex International, in partnership with the UPHF in Valenciennes, is developing a range of lead-free piezoelectric targets: BNT-BT, KNN, NBT, etc., with performances comparable or even superior to PZT targets.

The objective is to develop reliable process for manufacturing marketable ceramic targets of NBT, NBT-BT and KNN, with a relative density > 90%, with controlled stoichiometry and while avoiding the volatility of alkalis.
