LAGP, or Lanthanum Aluminum Gallium Phosphate, is a type of ion conductive ceramic material that can be used as a substrate in a variety of applications. It has high ionic conductivity and good chemical stability, making it suitable for use in high-temperature applications. LAGP has a range of potential applications, including in fuel cells, batteries, and electronic devices. However, its relatively low mechanical strength compared to other ceramics, as well as its sensitivity to moisture, can make it challenging to work with.
