Research Progress of Manipulating Composition and Properties of Ceramics via Liquid Precursor Infiltration Technique

Liquid precursor infiltration technique is capable of incorporating a desired content of exotic elements with controllable distribution. The research history and progress of infiltration technique are reviewed, which demonstrated its features by analyzing mass transferring mechanisms, the types and properties of the green body and precursors, and unveiled the possibility of manipulating the composition and properties of the final material via adjusting infiltration processing parameters. The preceding investigations confirm that as a general strategy, liquid precursor infiltration technique boasts the potential of wider application for other materials, since it possesses the unique advantage in achieving minor content doping with high homogeneity, surface modification, gradient and functional materials and could serve as a promising technology in the future.
