It is reported that BaTiO 3 powders had been coated with Nb 2 O 5 by hydrolysis of Nb alkoxide. The objective was to produce homogeneous Nb 2 O 5 -BaTiO 3 materials. Electrical properties and microstructure of BaTiO 3 -1%Nb 2 O 5 were determined. The grain size was finer in the material with Nb 2 O 5 suggesting...
It was reported that air atomized Al alloy powders had been reaction sintered with additions of air atomized Al-SiC powder in N. An Al-AlN-SiC composite was produced. This was shown to have high mechanical properties and wear resistance. Typical shrinkage of pressed and reaction sintered material was 0.8%. The composites were considered to have potential as a replacement for nodular cast iron...
