| Abstract | ||
| This research is a treatment trying of the Barium ferrite properties which obstacle the using its as an absorbent materials for Radar waves. These obstacles are the high cost, bad mechanical properties and heavy weight, The solution is prepareing a new composite material , its matrix is the kaolin and filled by Barium ferrite. 5% and 15% of barium ferrite have enhanced the mechanical properties of prepared a samples pressed at 69.4 Mρa and sintered at 1150 C˚ for two hours and 2ºC/min. and 3ºC/min as a heating and cooling rates respectively. The first percentage has a (0.224) reflective index for 0.8 GHz and 2mm thickness and (0.093) for 10.4 GHz and 2mm thickness. | ||
