摘要：

Tungsten　bronze　Ba0.5Sr1.5Na0.6K0.4Nb5O15　ceramics　with　97%　theroetical　density　have　been　prepared　successfully　by　CO2　laser　sintering.　The　laser　power　rising　rate　of　1　W/s　is　the　best　technical　parameter　for　obtaining　dense　ceramics.　The　temperature　field　analysis　reveals　that　the　lower　rising　rate　of　power　can　avoid　the　appearance　of　hollow　structure　in　the　sample.　©　2009　IEEE.
