A ternary silicide Ca(Al[sub 0.5],Si[sub 0.5])[sub 2] was prepared by Ar arc melting. Powder x-ray diffraction measurement indicates that it has the AlB[sub 2]-type structure with lattice constants of a=4.1905(5) and c=4.3992(8) Å, where Si and Al atoms are arranged in the disordered honeycomb lattice and Ca atoms are intercalated between them. The silicide is isostructural with a superconductor MgB[sub 2]. Electrical resistivity and dc magnetization measurements revealed that it is a superconductor with a T[sub C] of 7.7 K. © 2002 American Institute of Physics.
