If you are interested in recycling, please contact us. At Amphenol-ASTG, we make Quality, Safety and Environmental Protection a top priority. The prerequisite is that the piezoceramics are delivered without foreign components (i.e. Piezo Technologies Headquarters, Manufacturing & Product Development. This is why, for example, lead compounds in ceramic compounds are exempt from the ban in the "End-of-Life Vehicle Regulation".ĭespite this, or precisely because of this, we want to support our customers in this respect: CeramTec offers to take back piezoceramic components and to dispose of them in an environmentally friendly way or to recycle them. This is also the view of the European Commission. The main component of piezoceramic components are lead compounds such as lead zirconate and lead titanate. CeramTec's Multifunctional Ceramics Division sells ceramic components and is therefore not directly affected by this directive - but our customers may be. This directive describes the avoidance of hazardous or harmful substances in electrical or electronic equipment. RoHS: Directive on the Restriction of the use of certain Hazardous Substances in electrical and electronic equipment. RoHS Directive - Recycling of Piezoceramic Components For this reason, they are very suitable for automotive applications in the area ranging from –40 to +160º Celsius.Īdditional special materials are available upon request. SONOX® P502 and SONOX® P504 are specially developed materials with a high rate of thermal and temporal stability. Sensor applications are mainly combined systems in which the piezoceramic is used as ultrasonic-transmitter on the one hand and as a receiver on the other hand.

High piezoelectric activity (d33 ≥ 400 * 10-12 C/N).Materials for sensor applications SONOX ® P5, SONOX ® P502, SONOX ® P504, SONOX ® P508, PZT 503, PZT5A1, PZT 5A4, PZT5H1 Materials of this type are specifically well suited for high-performance ultrasonic applications in the range from 20 kHz to several MHz. High mechanical quality factor in between 5.These materials withstand both high electrical driving voltages and intense mechanical (pressure) loads and are characterized by: Materials for power transducers SONOX® P4, SONOX ® P8, PZT401, PZT807 The following material categories are differentiated: Besides the typical parameters (see data sheets), selection criteria include behavior under high electrical and mechanical loads. Piezoceramic materials are categorized according to their chemical composition and, on the other hand, by the specific application conditions. With their different qualities and application options, SONOX® and PZT materials are synonymous with premium efficiency and maximum reliability in the world of sensors and transducers. High-Performance Materials for Piezo ApplicationsĬeramTec has developed special highperformance materials for implementation in piezo applications, as piezoceramic components are sometimes exposed to high stresses, and must still fulfil their functions with maximum reliability.
