Abstract

In the present work, SiBCNO-based ceramic as high temperature adhesives are fabricated by polymer derived ceramic route. The effect of polysiloxane (PSO) and TiB2 on the microstructure and high temperature strength is studied, and the toughing effect of TiB2 is discussed. The highest adhesion strength of the joint (S12) reached up to 18.95 MPa at room temperature and 12.3 MPa at 1000 degrees C in vacuum after pyrolysis at 1000 degrees C in air for 2 h. It is interesting to find that the crystallization of nano-SiO2 reinforces the strength and thermal stability of glass phase with the addition of PSO, besides, the TiB2 plays the important role in improving adhesion strength by bearing load and facilitating the formation of stable SiO2-B2O3-TiO2 glass.
