The World of Electronic Ceramics: An Overview
Electronic ceramics, also known as electroceramics, are a class of ceramic materials primarily used for their electrical properties. While ceramics have traditionally been admired for their mechanical, thermal, and chemical stability, their unique electrical, optical, and magnetic properties have become increasingly important in many key technologies.Get more news about Alumina Ceramic Substrate,you can vist our website!
Electroceramics are distinguished from other functional ceramics, such as advanced structural ceramics. Developments in the various subclasses of electroceramics have paralleled the growth of new technologies. Examples include ferroelectrics used in high dielectric capacitors and non-volatile memories, ferrites used in data and information storage, solid electrolytes used in energy storage and conversion, piezoelectrics used in sonar, and semiconducting oxides used in environmental monitoring.
Dielectric ceramics are used for the construction of ceramic capacitors. These include materials such as Lead Zirconate titanate (PZT), Barium titanate (BT), strontium titanate (ST), calcium titanate (CT), magnesium titanate (MT), calcium magnesium titanate (CMT), zinc titanate (ZT), lanthanum titanate (LT), and neodymium titanate (NT), among others. Some piezoelectric materials can also be used; the EIA Class 2 dielectrics are based on mixtures rich in barium titanate.
Electronically conductive ceramics include materials like Indium tin oxide (ITO), lanthanum-doped strontium titanate (SLT), and yttrium-doped strontium titanate (SYT). Fast ion conductor ceramics include materials like Yttria-stabilized zirconia (YSZ), gadolinium-doped ceria (GDC), lanthanum strontium gallate magnesite (LSGM), and beta alumina.
Commercially used piezoceramic is primarily lead zirconate titanate (PZT). Barium titanate (BT), strontium titanate (ST), quartz, and others are also used. Magnetic ceramics like Ferrites, including iron (III) oxide and strontium carbonate, display magnetic properties. Lanthanum strontium manganite exhibits colossal magnetoresistance.
In conclusion, electronic ceramics are a fascinating class of materials that have found extensive application in modern technology. Their unique properties make them indispensable in various industries, and ongoing research continues to expand their potential applications.
