This paper describes a novel experiment involving the joining of alumina using a polymer blend method and Al foil. Alumina pieces were dipped into a polymer blend containing polycarbosilane and polymethylphenylsiloxane, which is a kind of polysiloxane. After curing and ceramization of the polymer on the alumina pieces, the pieces sandwiching Al foil were heated under vacuum at 1073 K. The samples near the center of the joining area (SC samples) were mainly composed of metal Si without any cracks, and their average tensile strength was very high, approximately 252 MPa. On the other hand, the samples on the periphery of the joining area (SP samples) were mainly composed of a carbon-rich substance such as aluminum carbide with deep cavities, and their average tensile strength was poor in comparison to the SC samples, approximately 56.9 MPa.
