Al 2 O 3 /Ni nanocomposites were prepared by a chemical method and hot-pressing technique using Al(NO) 3 .9H 2 O and NiO as the starting materials. At 1450 o C the composites can achieve >98% theoretical density after hot-pressing. Microstructural results revealed that Ni grains were uniformly dispersed in the Al 2 O 3 matrix, some fine Ni...
