The global market for technical ceramics is estimated to be valued at $96 billion in 2020 and projected to expand at a compounded annual growth rate (CAGR) of 7.4% through the next five years. Currently, ion-conducting ceramics (ICCs) occupy a very small share of this market—$167 million in 2019—but are projected to have very healthy growth through 2025, rising at a CAGR of 13.1% to reach $338 million.

ICCs are a group of materials characterized by distinct properties related to their capability of conducting positive and negative ions. The most common ion-conducting ceramics are based on fluorite-type oxides, phosphates, perovskites, and garnet-type oxides. Some of these materials have been engineered to have ionic conductivity close to those of liquids.
