An air stable high temperature adhesive from modified SiBCN precursor synthesized via polymer-derived-ceramic route

The high temperature adhesives are required in most critical applications such as nuclear and aerospace technology. To obtain an adhesive with high temperature bond strength and low synthesis temperature, polysilazane (PSNB) was modified by PBSZ, PSO, nano-Al2O3 additives. Effect of the SiO2 to B2O3 ratio and curing pressure on microstructure and high temperature bond strength has been investigated. After curing and heat-treating at...
