Several preparation methods of ceramic ink for jet printing forming are reviewed and the related research work is reported. Although the dispersion method is simple, its dispersiveness and stability are not good enough for jet-printing forming. Fine particle size in ceramic ink can be obtained by sol methods and its dispersiveness is much better. Unfortunately,its stability still requires to be improved further to match the needs of forming. The reverse microemulsion has excellent dispersiveness and stability, and can easily achieve the dispersion in nanometer level. However, the problem of low solid content in reverse microemulsion should be solved by taking effective measures.
