For AN-BN system, substantially Sm2O3, Y2O3, CaF2 as a sintering aid, but the oxide sintering aids may introduce oxygen in AlN-BN ceramics, which is not conducive to performance AN-BN composite ceramics.
For the AN-BN system, Sm2O3, Y2O3, CaF2 as the sintering aid, but the use of oxide sintering aids will be used in AlN-BN ceramic oxygen elements, which is not conducive to the performance of AN-BN complex ceramics.
For an-bn system, Sm2O3, Y2O3 and CaF2 are basically used as sintering aids, but the use of oxide sintering aids will introduce oxygen into AlN-BN ceramics, which is not conducive to the performance of an-bn composite ceramics.<br>
