Joints　between　reaction-bonded　silicon　carbide　(RBSiC)　and　joints　between　pressureless　sintered　silicon　carbide　(SSiC)　were　produced　respectively　using　a　polysiloxane　silicon　resin　(YR3184,　GE　Toshiba　Silicones)　as　joining　material.　Samples　were　heat　treated　in　a　nitrogen　flux　at　temperatures　around　1200　degrees　C.　The　maximum　three　point　bending　strength　of　the　joints　between　reaction-bonded　silicon　carbide　is　197　MPa.　The　maximum　three　point　bending　strength　of　the　joints　between　sintered　silicon　carbide　is　163　MPa.　The　join　layers　are　continuous,　homogeneous　and　densified　and　have　thickness　of　2-5　mu　m.　The　joining　mechanism　is　that　the　amorphous　silicon　oxycarbide　ceramic　pyrolyzed　from　YR3184　acts　as　an　inorganic　adhesive.　(C)　2009　Elsevier　Ltd　and　Techna　Group　S.r.l.　All　rights　reserved.
