摘要：

Silicon carbide (SiC) samples have been joined by a pressureless slurry based method. The CaOAl2O3 (CA) glass-ceramic joining material has been characterized in term of crystalline phases and thermal and mechanical properties. A torsion test based on miniaturized hourglass shaped specimens has been used as pure shear strength test method for joined ceramic samples. Torsion results are compared to those obtained by a single lap offset (SLO) test in compression on the same joined materials. Pure shear strength of 104 +/- 25 MPa has been measured by torsion test, whereas single lap offset gave 36 +/- 8 MPa.
