High purity layered YbB 2 C 2  powder is synthesized by a boro/carbothermic reduction method using YbBO 3 , B 4 C and graphite powders as raw materials. Its X-ray diffraction data are presented, and the space group  P 4/ mbm  (No. 127) is confirmed. The lattice parameters are  a  =  b  = 5.3389 Å and  c  = 3.5683 Å, and the atom positions are Yb (0.0000, 0.0000, 0.0000), B (0.3621, 0.8621, 0.5000), and C (0.1606, 0.6606, 0.5000). Porous YbB 2 C 2  ceramics have a high porosity in the range of 69.89–58.11% and a high compressive strength in the range of 19.49–63.44 MPa. Furthermore, the as-produced porous YbB 2 C 2  ceramics show unique chemical activity. Porous YbB 2 C 2  ceramic with a porosity of 69.89% emits so much heat that it can burn a piece of paper when this ceramic is wetted by water. The rate of reaction between the porous YbB 2 C 2  ceramic and water can be simply controlled by adjusting the porosity. The solid reaction products are YbB 6 , C and an unknown amorphous phase.
