Polyborosilazane‐Derived High Temperature Resistant SiBCNO

One of the main features of SiBCN‐based ceramics is their high temperature stability with respect to crystallization and decomposition in protective atmospheres. High temperature studies of a polyborosilazane in air up to 1500 °C show that the formation of coexisting nano‐quartz and amorphous B 2 O 3 is suitable for the application as adhesive for bonding advanced ceramics. Spectroscopic and X‐ray studies combined with thermal analysis clearly...
