Final Report - IMMEDIATE (Inexpensive, high-performance, lead-free piezoelectric crystals and their applications in transducers for ultrasonic MEdical DIAgnostic and industrial Tools and Equipments)

Project ID: 17569
Funded under: FP6-SME

Abstract

The European funded IMMEDIATE project constituted an effort to seek alternative lead-free solutions for piezoelectric materials used in medical and industrial devices, as well as in a wide range of other applications.

This effort was supported by the following activities which mainly focus on the needs of the participating Small and medium-sized enterprises (SMEs):
1) study the Solid state crystal growth (SSCG) method to prepare inexpensive lead-free potassium niobate crystal (KNbO3) and modified potassium niobate crystals. The method lay on template-assisted growth of single crystal from high-density ceramic substrates and presented a potentially cost-effective way to obtain crystals of complex compositions that are difficult to prepare with standard techniques;
2) development of medical and industrial transducer components based on high-performance piezoelectric crystals and ceramics of lead-free potassium niobate and novel modified potassium niobate compositions. The morphotropic compositions of modified potassium niobate and the special crystal orientations of the potassium niobate led to performance advantages compared to lead-based piezoelectric ceramics.

The long-term objectives of the project were to help:
- reducing lead-based toxic wate during the production of piezoelectric materials and components;
- eliminating toxic lead-based compounds from medical and industrial ultrasonic imaging devices and ensure safer disposal;
- develop bio-compatible piezoelectric materials.
