2.02.8 Concluding Remarks

improvement in the alumina matrix CNTs bonding in the sintered state (Cha, Kim, Arshad, Mo, & Hong, 2005;

Cha, Kim, Lee, Mo, & Hong, 2005; Lee et al., 2011).

Some of these methods have had some successful results for relatively small specimens; however, scaling is still difficult. Therefore, till date, there are no reports of defect free high-density pieces to be commercialized. In the same way as CNTs, boron nitride nanotubes/alumina composites are being investigated. Fabrication of dried mixtures by HP has been reported (Wang et al., 2011).
