Low thermal expansion ceramics are defined as ceramic materials with a thermal expansion coefficient below 2.0x10-6 °C-1. Compared to other conventional ceramics, these materials exhibit exceptional resistance to high temperatures and thermal shock, maintaining stability in complex environments characterized by high temperatures and abrupt temperature changes. They find widespread application in various fields, including refractory materials, catalyst carriers, electronic devices, and aerospace. This article reviews the classification, preparation methods, and application domains of low thermal expansion ceramics, and examines the research advancements of several common types such as cordierite, aluminum titanate, NaZr2(PO4)3, and lithium ceramics. Additionally, the article discusses the development trends in this field. [ABSTRACT FROM AUTHOR]
