| Y2Si2O7 | Solid state reaction， sol-gel | Excellent resistance to high temperature water vapor | High requirements on the antioxidant properties of the fiber |
| LaPO4 | Sol-gel | Good compatibility with oxide （Nextel fiber） | The thermal expansion coefficient is much different from SiC； the existence form is related to oxygen partial pressure |
| CaWO4 | Sol-gel | High thermal stability | Calcium salt corrosion |
| ZrGeO4 | Sol-gel | High thermal stability | |
| ZrSiO4 | Sol-gel | High thermal stability | |
| MAX phases | CVD，EPD，molten salt reaction | High interlaminar bonding strength | CVD method will produce more by-products， and the molten salt reaction will damage the fiber |
